My best ever orgasm was fairly recent. A guy came over, we got naked and eventually I sat on his hard cock, taking it up my ass, riding him cowgurl style. I got so turned on riding his cock that I shot a huge load all over his chest. An I still think that I am mostly straight. LOL

Best was after edging for a few hours and then shoving a vibrator in my ass and setting it on my prostate, I've never come so hard or so much since.

My best was when my wife was fucking my ass with a strap on dildo i didn't think I could cum so much.

The very first one definitly stands out. What a revelation that was. Been hooked on that feeling ever since.

"Firsts" are always memorable... first masturbation orgasm; first handjob/blowjob/fuck. I don't remember my first "edging" masturbation session, but edging for an hour has always produced stunning orgasms ever since.

That would be pretty hard to forget! Lucky you!

It's hard to tell after having thousands of orgasms in my life, but I guess the best ones were while masturbating, like when I stole a friend's boxers and sniffed them, feeling that amazing male smell while masturbating.
