So many of us can relate to this. It isn't a problem as long as you switch to oral or manual to please your woman and then followup with a nice long round two.
Haha sometimes the pussy is just too good. Happens to all of us bro nothing to be ashamed of. Though you probably knocked her up with that huge cock. A problem i wish i had hah
My ex-wife once made me cum five times in a minute. She left me for a guy that could go for a long time; of course, his cock was a whole lot bigger than my 4.5 x 4 inches, so it could have been that as well.
