My cock is thicker than what most men have already experienced, which is why I take my time working it in instead of just shoving it in to start. Once I get them used to being stretched open for my 6-inch circumference, I start fucking in earnest. Those I'm breaking in, though, can usually only take it 15-20 minutes that first time; but, they always say they'll want more of it soon. There's one guy who has wanted me to fuck him for the longest time; but, his ass is tighter shut than a vice--he hasn't said if he's taken any of my suggestions to help him prepare for getting fucked. About 5 years ago, a 22-year-old practiced (his word) with a thicker-than-average dildo; when we met after about 4 months, he took my bare, thick cock like a champ and longer than I expected--he told me on the way to the park (where we ended up fucking in the back seat of my car because it got too cool) that he had not yet been fucked and wanted me to be the one who broke him in. One night, I went to a park that's been successfully cruisy for years; it was busier than usual when I found 2 pairs of guys next to each other fucking--when the boyfriend of one saw my cock, he pulled out and told me to start fucking, but the bottom said, "Not with that big cock!", so I just fed it to him in a spitroast.
