In my freshman year of college I was in a rather fortunate place and time where I hung out with/ met girls, then flirting would lead to one thing or another and sex would happen. I never kept their numbers and such in my phone or friended them on FB, because it was always clear that we were pretty much fuck buddies,I mean we would still hang/go out, but nothing more. I had a little black book but that got lost when moving out of the dorms/into an apartment. Now the only way for me to get sex now is if/when i get into a committed relationship (Hopefully soon with this one girl I really like), because well I've calmed down some. Do i regret anything? No. Am I Ashamed/gonna hide it? No. Was it fun? hells yes. I consider myself guilt-free because all the girls were just looking for some fun, and still hung out as friends and such, and there was one case where she and I kinda looked to go on farther, but it ended up not working out, so whatever
