It doesn't matter if you're new to having sex. It shouldn't be painful for you. The man isn't the only one who's meant to enjoy the experience. You should be feeling just as much pleasure as he does. If sex has been super painful for you, then here are a few reasons why:
Urinary tract infections are common, but they're pretty painful. They cause you to feel like you have to pee every five seconds, even if you've just went to the bathroom. They also make sex feel incredibly painful. Don't worry, because they're not STDs. You can't give them to your partner by sleeping with him, and a doctor can give you medication that'll clear them right up. If you take the meds you're prescribed and drink plenty of water, then the infection will clear right up and sex will feel comfortable again.
Women take a while to get ready for sex. If your boyfriend undresses you after one or two kisses, then you probably won't be sufficiently wet down there. That means sex is going to be painful for you. In order to fix that, you need to engage in more foreplay than you usually do.
If you've slept with a few men, but haven't been checked for STDs, then that needs to change. Don't worry, because most STDs can be taken care of with medication. Even if yours can't be cured, there's probably some sort of medication that will dull the symptoms, so that the disease is more manegable.
Since your man finds you super sexy, he might go a little crazy during sex. If he's so rough that he's hurting you, then he needs to calm down. In order to fix this, you should get on top of your partner. That way, you'll be the one in control of the depth and pace.
Some women are naturally dry down there. If sex hurts, even if you're super turned on, then you should try using lube. You can buy it at any drug store. All you have to do is rub some of it on your boyfriend before you have sex, and it'll make the experience feel more pleasurable for you.
Your brain might be making sex hard on your body. After all, you need to be completely relaxed in order to have sex. That's why you should only sleep with someone you're completely comfortable with. You should also try doing Kegels to learn to learn how to relax your muscles down there.
There are a few other problems that could be causing sex to hurt. However, in order to find out if you have one of them, you should visit your gynecologist. She should be able to examine your symptoms and tell you what the problem is. She might even be able to fix it for you!
You don't want to continue to have sex if it's hurting you. You need to figure out what's causing your discomfort and fix it. Is sex fun for you or is it painful for you?
