I would say between 5 and 8 inches. But it's all relative. I like to suck a lot, and a small penis is nice to put it in my mouth whole with testicles and all. On the other side, I've had a couple of bad experiences with very big ones, they looked fabulous but when they tried to get them all inside me there simply wasn't enough room and they hurt me (I'm not into pain!). So, I'd say if it's going to be really big, it be be so in width rather than length.

Yes, twice. Once his cock was so large it was really hurting me. The other was with this bloke I liked so much and it was our first time, and I needed to pee so badly (too many pints at the bar), I preferred to risk getting him disappointed that peeing all over. He was gentle.
