So i've been dating a girl for a couple of weeks now and so far its been completely non sexual. She is a really taken home to Mom kind of girl. Well she was joking around last night to one of her friends about one of her ex's being so big, and the details came out that he was 7-7.5ish. I wanted to step up and share some dimensions but I didn't. What would be the most appropriate way to share them with out sounding really really arrogant or cocky? (Which i'm not) But I am much larger than her ex.
