I believe the woman I lost my virginity to was 36 at the time. I was 22. That would be my biggest gap, I think. I did fool around with a woman in her thirties (not sure how old) when I was 15, though, but did not have sex with her.
That time I lost my virginity was a sort of unusual situation, not typical of my relationship with this woman. I did date a woman 9 years older than me for several months when I was 25.
Wow… I feel so young now! I’m just 17 and now I don’t feel so bad about my first ‘boyfriend’ who was 19 when I was 14. Hmmm… then that same year I had another 19 y.o. BF. I really should’ve learnt the first time that it’s a good idea to stay away from my cousin’s friends… sigh…
So anyway, my biggest gap has been 5 years older. My youngest BF was gasp a whole 7 months younger than me (I was 16). And my boyfriend now is GASP 6 days older than me 
The biggest age gap for me has been 4.5 years. I feel like such a loser. I guess it looks good for me when I get into my 40s though huh? 
The ex wife on the other hand wanted no part in guys her age, out of the ones that I know 5 or 6 were at least 20-30 years older then her. She is now dating some guy at least 20 couple years older. She told me she didn’t know him when I left but hmmm intersting that he was there a week later. Guess she couldn’t cut it with someone her age.
interesting what your username does to the page…
I married mine—he’s 13-1/2 years older than me. Now I’m 44 and he’s 57! Seems stranger than 30 and 43, when we met. Hell, he’s almost 60. We’ve been together for 14 years, though.
