Expert Q & A Answers About first time sex

We want to have sex for the first time, but it hurts! What’s the problem?

My boyfriend and I are both virgins...but we tried to have sex for the first time a couple nights ago. When he started to enter me, I felt a sharp pain. He could put the full length of his fingers in me comfortably, but his penis caused me pain. So we ended up not doing anything. Do you have any advice?

Is it normal to bleed after sex...the first time?

I had sex for the first I always feel like I have to pee and my penis sort of tingles. Is this an STD?

I had sex with a girl and later that day, I felt like I always had to pee...but very little urine came out, and my penis sort of tingles. Is this a symptom of an STD? If so, I thought that it took a while for symptoms to occur, not the same day. She’s my first sexual partner.
