Mine's 8x6 (actually more like 7.5x5.5 except when I'm super excited and it goes to full mast), and most guys seem to think I'm "very hung". I've certainly seen quite a few bigger ones, but it's well above average. It's a really nice size for sex, and guys seem to enjoy it a lot.
I'm nothing like a strict bottom, but I enjoy bottoming very much and really don't want to top all the time. So it's really annoying that a lot of supposedly versatile guys just want to bottom when they meet it. Especially if they're oral, not anal, or if they think it's too big to take anally, because it's not super sensitive and oral topping doesn't usually get me off.
The other time it's a drawback is when it won't stay really hard - that happens quite a bit with tighter bottoms or if I'm not that into a guy for whatever reason, or sometimes just because my various meds are causing issues. If it were smaller, I think it would be less trouble that way, but the way it is, I generally can't get back into a guy if it's not good and hard.
So, some good, some bad. My only regret is that I wish I'd realized at a younger age that it was above average and that many guys are attracted by that. In my 20s I had no clue.
