text: advice needed abt sex? when i had sex wid ma girlfrnd first time , i had a severe pain into ma penis.it got stiff nd iched the following 2 days.what shud i do during sex so tat the prob doesnt persist in future well if u used a condom, u might be allergic to it. and if you didn't and she was a virgin, she may have been a little tight for you and caused irratation. make sure to wash after you do it and wear a condom if you didnt. if she wasn't a virgin, maybe she has something and might have given it to you. you may want to see a doctor and get tested, and have her tested too.
