I'm a guy, and my first partner wasn't a virgin. She was a married woman on my college course - her husband was away working for some weeks. I remember we petted a lot on a couple of occasions and finally one of these was at her place and we ended up in bed - 'somewhere more comfortable' she said. I had such intense and joyous delightful feelings just from the touch of our skin and holding her and being held. When I recall the moment we first had sex, I get the memory of such intense feelings as I penetrated her vagina that if I were to represent the moment in a picture, there would be rays of intense light emanating from our genitals. I remember the feeling of being inside her, and the feeling of our pubic hair touching. I also remember her realising after my orgasm that this was my first time - and being very appreciative that I could continue until she had an orgasm.
