I definitely prefer a larger guy...not gigantic, mind you, cause those hurt...but bigger and thicker is always better in my book. My partner (thank the Lord) is very well endowed - about 8" long and 6" around. I've been with guys who were shorter, but if they're at thick, that works just fine. The smallest I've been with, and I'm not kidding, was no more than 3" long and 3" around, and let me tell you - I couldn't feel a damned thing!
As I mentioned in my post about our first experience the other night, I really felt like I got the short-end of the stick, pun intended. With my partner being as large as he is, I've really gotten used to enjoying a good size and I knew the chick he was banging that night was feeling pretty good, seings how I was with her hubby and he was about 1/2 the size of my guy. Sorry guys, but I want a nice, big, thick dick...and at the next party we go to, I'm going to make sure that's what I get...there's gotta be a fair exchange next time, lol!
