Missing my first and only time.

Straight M22, I have had sex only once in my life, lost my virginity when i was 17 with an older girl who was 26 that time at a family function and she was bride's best friend, she and other friends and me because i close family, stayed at bride's house for the night after seeing off the Bride and other relatives were at some hotel, so her and her friends were having a drunk party and I was up in my room, fresh out of shower just changed into my sleeping clothes and I went to bathroom and came back and got startled on seeing her in my room and next thing i remember was a little dialogue and me finding out that she was drunk and us having a hot, raw, groping sex together for next 20 minutes, she came first and after 5 min I too came on her butt and we cuddled up for another 10 minutes chest to chest, after she was half asleep, I got her cleaned up and carried her to the next room and left her on the bed. I miss her and can't do anything about it, because we had absolutely zero talk after that and we never got to get into contact with each other, but i seriously miss that moment a lot. Now I haven't had sex in like 5 years now ,can't manage to get someone to have a casual fuck for once, I miss that feeling.
