Hello, my problem is that i find extremely difficult to wear a condom. I have measured my penis lenght:18 cm and my girth: 17cm and I think it's pretty much average so, why can't I put on a condom without being so tight it cut my blood flow…Any serious advice would be welcome. Thanks.

Hello, I stayed round my boyfriends 2 nights ago and we thought it was time too have sex he's done it before but it was my first time. He never put a condom on and I'm not sure why? He put his penis in slowly but it was very painful. Eventually we had too stop because it really hurt. I'v been sore the past couple of days and I thought thats because I'v been stretched open a little bit. I'v just come out the shower and there was a tiny tiny bit of blood what is this?

i have these paper cut things around the inside of my lips of my vagina and I've never had unprotected sex,I've only had sex with one guy and I am very safe. I don't keep them but I get them every once in a while. They don't itch or anything just sensative if I'm like rubbing or something..I don't know what it could be so I thought I would ask before I freak out.lol
