Greedy or not I just can't do that. It's not the same to fuck a girl that you don't care about, especially after you've been with a woman or women that you've committed to for a significant period of time. It feels too awkward, too sloppy and you've got the risk of STDs and fuckloads of drama afterward.
I was courting a chick who I had a huge crush on in highschool after I broke up with a crazy chick... turns out she was extremely horny and wanted to fuck real bad but as crazy as it sounds, it was a turn off. I just finger banged her highschool style and didn't let it go any further. I slept over a couple of times but didn't bang her. Seeing her act like that really changed my opinion of her fast. I had a crush on her for years before that... Turns out that she wasn't really too slutty or anything, but I just don't like a girl who'll fuck someone that easily. It's much different being in a relationship.
I'm not sure if it's just my personality that makes girls feel comfortable, but my three longest relationships were all with virgins. And they were all, BY FAR, the freakiest!!! Girls in a comfortable, committed relationship will put out. I see no huge rush to bang some slut from the club and wake up with festering sores 3 weeks down the road.
