Had a few say i ruined them for other men,
first one was my first fuck buddy, we were 21 she'd lost her virginity a week before to a guy that was apparently small and finished as he stuck it in, she was a little naive and apparently didn't realize large penises were real outside porn, she was hooked after the first time, we were casual for a while till she wanted to get serious, we called things off cause i wasn't interested, few months later she came back for more, we had an on again off again things for a few years till i got bored, one time i called her on why she kept coming back for more just to eventually say we were done for good again. She said she wished we had never met and hooked up because although i technically wasn't her first, i certainly broke her in and set a bar that she compared other guys too and very few lived up to her sexual expectations
Second was an old friend who i got into an affair with, she was married to a guy with a small dick, severe premature ejaculation and slight ED, a one time thing turned regular for several years until she divorced and started dating again, she went through a LOT of guys before settling down and getting married again to a guy i actually used to know. they stopped by one evening when they were in the neighborhood, had a few drinks then she got a bit weird said she had a headache and they left. The next day i got a text apologizing for leaving so abruptly but also saying we probably shouldn't ever be alone together because the real reason they left is she couldn't help but notice my bulge and after a few drinks she was so horny she started fantasizing about fucking me right there and even thinking about purposely leaving something just so she had a reason to return. Said she loved her husband and he had a large cock length wise but she'd never been able to enjoy an orgasm the same after having my thickness.
Third one i didn't just ruin her i changed her. I met her through an ex, 23, shy nerdy good girl taylor swift look a like, she'd had one short term boyfriend since i've known her, knew lots of guys who tried but got no where, she was always judgemental of the sluttier girls and casual sex in general. After i broke up with my ex we hung out a few times and i was trying but wasn't having much luck and was about to give up then one night she comes over with drinks, she asked for a massage and from there it didn't take long to talk her out of her clothes, her eyes almost jumped out of her head when she saw it for the first time, we tried fucking but she was so nervous i couldn't get it in past the head, i ended up going down on her till she had an orgasm something she'd never experienced before and she gave me a hand job because she didn't give blowjobs. The first time i actually fucked her i asked if she was virgin cause she was so tight, she insisted she wasn't and i ended up fucking her to once of the most intense orgasms i've ever seen, it left her shaking and convulsing for like five minutes. It wasn't long before i was fucking her several nights a week, one of us would text at any hour, she'd come over fuck and I'd send her on her way, if i was extra horny i' have her spend the night and fuck her brains out, it took some work and with holding oral before she came around to giving head and 5 years later shes pretty damn good, then popped her anal cherry in the past year she wasn't fond of it at first but now if she's been drinking she'll ask for it. Few months ago she came over late one night after a wedding, pretty drunk, we fucked and afterwards i asked if she'd gone to the wedding solo or bailed on some poor date, she just gives me this look and says no point in taking a date when she already knows once she's drunk the only thing that will be able to satisfy her is getting fucked by me, then she starts telling me how she wasn't like this before she met me, she'd never imagined sucking a cock, or having a guy eat her out, or being so horny she'd go to a guys house in the middle of the night just to fuck, or doing anal but worst of all she felt she had to hide her dirty secret which just makes her want it even more.
