I went to my girlfriends house and we kissed for a while, then we took our clothes off. We continued kissing and feeling eachother for probably around 45 minutes or so. I was hard for like this whole time, but when we decided that we wanted to have sex, and its almost as if all of the sudden i got limp. so we just continued kissing and just laying with eachother and stuff. Then when I had to go i was hard again. This same thing happened twice. It was alright because we were happy just laying with eachother but id still like to know what happened. I'm completely comfortable with her so the only thing i could think of was i was subconsciously nervous about doing it or i already had it up for a while. also this would be my first time, but not hers. Also i was wondering how sex fits into love. like, i dont know how to explain it, but can a good relationship become based upon sex and thats what its all about and would that ruin the relationship?
"Laying with eachother" Laying what? Paving slabs? Bricks? Cement? To lie: I lie You lie She lies, he lies We lie They lie We were lying... It just annoys me. Little things...
It is called "performance anxiety", and it is quite common for teenagers just starting out on their sexual adventures. My advice is just relax, and let it flow naturally - but if you do have sex, wear a condom.
