Being bisexual isn't all about being submissive for men. You can top, if that's what you want. You've got a big enough cock and the confidence to make another man take it. Imagine another man down on his knees in front of you, and you just sliding your tip right in his mouth. Put him on the ground. Make him arch his back. Fuck that hole. He likes it hard. Make him beg you to breed him. You've never wanted to empty a load more than you do right now.
