Are there any medications for pain-free sex?

Water-based lubricant that contains lidocaine.

Well what you need sweetie is a man that understands the purpose of foreplay, how to get a woman to naturally lubricate and slow insertion ;gradually building up momentum till It fits you like a old glove. If a vagina can push out a baby, you can handle any penis size. Stop hanging around with little boys. the entire trick is the initial insertion, and how quickly it happens, once pain is felt, that is the end of it, it will be painful throughout. Must be slow and easy, and nature will take care of the rest. If you need KY jelly, your with the wrong man.

I wouldn't recommend that you use any numbing medications down there. Make sure you are lubricated before sex. One good product is Play by Durex. You can get in the tingle sensation, which gives a tingling sensation that can take your mind off the tight feeling. Even very tight girls can enjoy sex if they are well lubricated. If it is agony i would recommend seeing a psycho sexual counsellor as it could be some fear that causes a spasm of the vagina which makes penetration difficult and very painful. Good luck

There are a couple of conditions that make intercourse difficult or impossible and if that were the case you'd need to see a doctor but you don't say it's impossible, just that you're tight and it's painful.

I would assume the problem lies in the technique of your partner. Wham bam rarely works out well for someone without a lot of experience.Your body has to be prepared to accept him. If your partner is inexperienced and unable to hold off and give you the attention you deserve before penetration you might want to suggest he masturbate before your next "date".
There's always oral sex, but as a woman, I wouldn't recommend it unless it's mutual. I suspect your man falls under the category of lazy or selfish lover and if that's the case it's not fair to you that it become your responsibility to get him off prior to your encounter each time. If it's mutual it kills two birds with one stone, he'll already have ejaculated once and will be able to take his time for the second round and you should be well lubricated.

are u new with the sex thing? as in did u just lose ur virginity?
if so, then all i can say is it goes away over time

you don't say how old you are, but if you are "new" at this, there can be some physical problem that would make it painful for you, and you would need to seek medical evaluation to make sure what may be going on

otherwise, more lubricant
