Hi Aunt Vadge,

What is it like for first-time sex? Like, what would happen with a female vagina the first time doing sex?

Dear First Timer,

The mechanics of having sex with a man for the first time are fairly simple in a physical sense, but there are a few things that make it easier and more fun. Sex should feel good, or at least not bad – if it hurts, that is your body telling you to slow down or change something, not to push on through.

So, to explain physically what you might feel when a penis enters your vagina.

The hymen

First, if you still have a hymen, you may feel some stretching or stinging at the entrance, and there may be a little bleeding. Have a read of everything you need to know about the humble hymen, and take a look with a hand mirror to see if you have one and what it looks like.

Hymens often wear away naturally over time, just from sport and everyday movement, so it is completely fine to have one, or not. If you do have a hymen and you would like to stretch it gently beforehand so it is less likely to sting or bleed, that is an option too.

The sex

Whether or not you still have a hymen, first-time sex can be pleasurable – but for most people it is also awkward, a bit funny, and not especially sexy. That is completely normal. Nobody is born knowing how to have sex, and learning takes practice for everyone. Everyone’s first time is an event.

Managing anxiety and vaginal tension

First-time sex can bring some nerves, because it is new and you don’t know what to expect. Nerves make your vagina (and the rest of you) tense up, which can make it hurt more than it needs to, because the penis then has to push harder against tight muscles to get inside.

So it really helps to keep calm, relax, and be with someone you feel comfortable with. It is much better to have your first time with a person you like, who likes you and wants to make sure you are okay, so you can say ‘ouch, that hurts’ without feeling like you are supposed to enjoy it.

Penis size varies from about a chicken wing to a fair-sized cucumber, but most sit somewhere in the middle. It is important to be wet – with your own lubrication that comes when you are turned on, and, especially for a first time, a water-based lubricant as well. If you are using a condom (which is a good idea), keep the lube topped up, because latex tends to soak up moisture.

The feeling

Say your hymen is already gone, either naturally or from gentle stretching. That takes the stinging and bleeding out of the picture.

The penis is guided in gently and carefully, between the inner labia (labia minora) and into the vaginal canal – see vag basics for diagrams. The first thing you feel is the head of the penis resting at the entrance, between your labia. Adjust yourself so it is nestled comfortably at the opening.

Then the hard penis starts to enter – slowly, no rushing, and not with a soft penis (that doesn’t work). As it slides in with plenty of lube, you will feel a fullness. You can squeeze your muscles to see how that feels, or wiggle a little and try different angles to find what fits best.

If your partner is new to this as well, you will both need to experiment and see what feels good. The penis should fit all the way inside without any problem, but as it goes in, relax your muscles and take your time. Look up how to have sex 101 to see how it all works.

If it hurts, change something – don’t let pain be the main event of your first time. You don’t have to ‘finish’ by thrusting or by him ejaculating. Your first time might just be your boyfriend putting his penis in for a second, pulling out, and that being that. Any version of this is completely okay. Go at your own pace, and if you stop feeling ready at any point, you can stop. First-time sex is a bit like swimming for the first time – if you have never done it, you have no idea yet what it should feel like. Practise.

Once the penis is all the way in, you can feel your vagina responding – maybe pleasure, maybe not much, maybe some pressure. The areas further up can feel quite pleasurable, or quite tense. You can start to move your hips in a light motion so the penis slides in and out a little, but not all the way. Make sure your clitoris is being stimulated too, by his body or a hand. Penetration without any clitoral stimulation mostly just feels like there is a big thing in your vagina, and not much else. You need to be turned on for it to feel really good, so keep the clitoris involved.

If your partner has a large penis, go extra slow, because it can reach all the way to the cervix and bump it. That can feel good when you are very turned on, but it can also be sore and uncomfortable. The cervix changes through your cycle – around and just after your period it sits low and firm, which can make bumping it more painful; around ovulation it lifts up and softens.

The overall feeling is one of fullness, grip and wetness. Having another person pressed against you, or you on top of them, close and kissing while their penis is inside you, is something you settle into. Keep yourselves comfortable so you can focus on the sensations, not on a crick in your elbow or a toe cramp.

First-time sex can be all sorts of things to different people, but the physical action is the same: penis in vagina. Aim for yours to feel, if not good, then not bad. There is plenty of time to practise and get it right.

Orgasm

You probably won’t orgasm, so don’t worry about it. Unless you already masturbate a lot and are very practised at turning yourself on and coming, there is very little chance of getting there during a first time – I have yet to meet someone who did. Guys may ejaculate, but they feel just as funny about it as girls do; physically it is usually an easier ride for them, because they do the entering and we get entered.

Tips for a good time

First-time sex is more comfortable with a partner you can talk to, plenty of lubricant (more is better – keep slathering it on), and keeping it short and sweet. Try for 5 or 10 minutes, then stop and try again another day. Longer penetration than that doesn’t start feeling better – fresh nerves make for the best sex. Save your flesh.

Short sex with lots of unhurried foreplay is a lovely scenario, so don’t skimp on the touching, kissing, licking and sucking before any penis goes anywhere near your vagina. If you get home from school or work, flop down and say ‘okay, jump on, Mick’, it will feel bad. If you make out and explore each other with tongues and fingers first, then try penetration, it feels much better. Have a look at fingering basics for young or inexperienced men and how to perform oral sex on a woman so you both have some tricks up your sleeves – get your partner to read them too.

If you would like to get used to having something inside you first, a small or medium vegetable (a carrot or cucumber works) can help. Be gentle, use lube, and touch your clitoris at the same time – being turned on makes all of it better. Getting a feel for it can take some of the surprise out of the real thing. A penis is warm and feels much nicer than a carrot, but it will give you the gist.

Use protection. You really don’t want to fall pregnant your first time, so use a condom every time, with plenty of water-based lube, and make sure your boyfriend knows how to put one on properly – there are good short videos online. Condoms are cheap, sold at any pharmacy, and you don’t need anyone’s permission to buy them. If a condom ever slips or breaks, emergency contraception works best taken as soon as possible, and a pharmacist can help you quietly.

A couple of hygiene basics so you don’t give yourself an infection by accident: have a wee after sex, and don’t move fingers, a penis or a toy from the anus to the vagina without washing first.

Take your time, be gentle, and keep at it – sex gets better the more you do it, but it takes a while to get the hang of. If it keeps hurting no matter how slowly and how wet you go, that is worth mentioning to a doctor or nurse; persistent pain with sex has causes worth sorting out, and it is a normal thing to ask about.
