I was talking to my girl (who before we met had never like truly done anything) and she kinda admitted to feeling a guy through jeans, which i was jealous as HELL at first, and i spent like two hours of the conversation trying to not ask the question that first came to mind (were they bigger) and all i could think was that this guy would have been like huge and it was driving me crazy, and i kept thinking what if she liked that more or what if it turned her on more so i kinda caved and asked and her response was "thickness he was a lot smaller like 4 around, and length he said he was 9ish but i didn't feel all of it and i think it was probably a little shorter than you are" she's not the kinda girl that says things to just avoid hurt feelings so at this point i completely stopped being jealous of the guy. So, this got me thinking, I've seen A LOT of threads about dudes on here so worried and jealous over their girl's bigger ex's, so it just kind of got me wondering what other guy's jealousy is caused by, like if you get jealous of them just for having done things with the girl that's now yours or do you just get jealous if they were bigger then you are?
