For me it is incredible. I totally love it. It is total heaven for me to have a man inside of me.
With some guys you really feel it, the throbbing, the pulsing, it is like he is exploding himself inside me. Most guys they get super hard, they twitch but you dont get that expanding and pulsing feeling. Some guys they only way you know they cum is from the noises and looks on their face.
For me, it depends on the position and the shape of their cock. If I am riding on top, or if I am on my back with my legs on their shoulders, you can really feel it well. Guys with banana shaped cocks that curve upright fit in me wonderfully, and i can usually feel everything they do in me.
I have incredible full body orgasms when getting fucked by guys. Its nothing like a regular male orgasm. It passes that level many time over.
