So I just started having sex with a great guy. I only started having sex about 9 months ago but I'm in my early 20's. With my first boyfriend, I definitely had some pain from sex, but I just attributed that to being a virgin. Condoms definitely aggravated that pain, but not always, and not horribly, though I think it got worse as it went on.
Now, after not having sex for about 7 months, not only does it feel like the penis is banging against my uterus (or something...which hurts), basically upon contact with the condom-covered penis my vagina just starts to burn and hurt pretty seriously. I have to stop sex after about a minute because it just hurts really bad.
Could this be an allergy to latex? In a way, I think that the muscle pain could be psychological, because since sex has always hurt, I don't enjoy penetration. But the burning definitely is very real.
What would be a ways to help this? I really want to have good sex. I am a person who loves being touched and being close with someone and I masturbate a lot, know my body well, and orgasm quite easily, but freeze up wherever penetration is involved.


A latex allergy could certainly explain part of the problem. As could a reaction to whatever lube you are using. Use poly condoms rather than latex and this should stop the burning sensation.
The banging against something would be your cervix which is the neck of the uterus that extends into your vagina to suck up semen and get sperm closer to the target - the egg. This indicates a positional problem We all get it hit sometimes and it is uncomfortable. If it happens commonly, it is time to try a different approach angle for the penis. In other words, experiment with different positions. Even the height to which you raise your knees or how far you spread can affect this.
You are likely spot on about the muscle reaction - it is your body trying to protect against pain as you have experienced it. This is another reason to try different positions that give you greater control. The greater control will give you greater confidence that you will not be hurt and then you can begin to relax. Start with any female superior position that appeals to you. Your partner needs to realize that you are dealing with a problem and focus on your comfort rather than his satisfaction. You can beat this - if he is understanding and supportive.
