Tenuous 61 years?
Every long-term partner I've had has been older. First age gap was 5 years, then 8 years, then 15 years (I'm currently single and slightly anxious that - should the pattern continue - my next partner will be drawing a pension. I'm 23.)

However, as regards age-gap shags, how about...

Me at 20, and 2 guys who gave their ages as 39 and 42. That's a combined age of 81.

Yes, at the same time.

I'm not proud of it, and don't remember most of the experience but what I do recall was extremely mediocre. They seemed pretty fucking pleased with themselves though.

Another good reason why I don't drink any more!

Hehe, I know what you mean
First boyfriend: 1 year older
Second: 4 years older
Third: 5 years
Fourth: 10 years

(These are only my serious boyfriends, all the flings and friends-with-benefits were between 6 and 18 years older)

Last week I kissed a man who is 51.
I've just turned 20...
Oh well, he was quite good-looking and fun to be around, I'm just concerned about the direction this is taking ;-)

Not just me then
Age is just a number, I guess! It's the exponential increase in the age gaps that worries me. I'm sure there's some weird Freudian reason for it all. Congrats on the 51-yr-old, I think you win :)
