My girlfriend and I have been having a problem recently. When we have sex, after a little while her labia becomes swollen and it's painful for her to keep having sex, or even be touched. Usually it's not a problem until we're done, but it gets annoying when we want to do it again that same day.

At first I thought it was an allergic reaction to latex or lube, but the same thing has happened when we have had sex with no condom and no lubrication. She's on birth control, could that have anything to do with it?

Vaginal sex fucking blows. It hurts like hell and doesn't even have anything remotely good feeling to make up for the shitty part. The only reason to ever do it is specifically to make your partner happy.

stop hurting your girlfriend, just get used to jerking off.

It sounds like cock rash. Basically, your cock is chaffing her vag because she's not wet enough, or isn't staying wet enough.

Lube it to the moon.

Personally, I'd go with foreplay, but you can use spit if you're lazy.

Wait, you can't even turn on your own girlfriend until the point where she is dripping wet?? :p:p:p:p

Have her to go her gyno. If it's not an infection or anything, make sure she's wet before you stick it in. Also, are you using studded/ribbed condoms?

Water based lubricants dry out too fast and silicone based become sticky after several minutes of use.

Lack of lubrication is probably the most likely problem she is experiencing. Try using lubricant and stop if she starts to feel sore. DO NOT use an oil or oil based product (i.e. petroleum jelly) if you are using condoms as it weakens the latex. A water based one that is fairly good is sylk - you can buy it at the supermarket or a chemist.

It sounds to me like she has a yeast infection. Ive had that about 5 times this year :/

You can get thrush from tight pants, washing with soap, taking antibiotics etc... it's really easy to clear up aswell... canesten cream is excellent!

I would suggest that she should see a gynecologist who will test her for likely infections in order to rule them out. I would definitely suggest seeing someone who is trained in gynecological health - not just the local doctor.
