Whats it like for a guy to have anal sex?

Physically speaking, the ganglion of nerves where your organs of pleasure SEND the messages is just about reachable by a penis entering the anus. Women like it for the same reason. The pleasure given is closer to the source and more intense.

For men there's another reason, if you've ever had a prostate exam... did you notice you liked it? Men with erectile dysfunction often train their partners to rub the prostate internally to increase pleasure. Even opposite sex couples will use that fact in tandem with blow jobs.

Sorry, graphic, but you asked.

Awesome

It's intense, is all I can say. I don't mind anal, it feels good if it's done right, but I like a little roughness so I don't mind some pain.

When the dude taking it shoots warm fudge all over his deep penetrating cock

It depends on the lube you are using.

It s like a ring on your kock
