For me, as a gay guy, the most important part of barebacking is the sensation of skin on skin. The transference of heat the body radiates. I prefer to shoot my load once i've pulled out. I want the visual effect.
If I was straight and in a long term relationship with a female, I would cum inside of her. In a relationship, that is where the trust factor "cums in" to play.
In a relationship (a real one) no partner should ever have to beg for anything.
