I LOVE getting my anus stimulated. Sometimes I use a vibrator. Other times I use a butt plug. I have better orgasms with a butt plug in when I'm having sex.
How much of a turn on would it be if your boyfriend/ husband had sex with another man? Would you simply just watch or join in?
Overall, I love getting sucked but it also has a lot to do with the girl. If the girl knows what she is doing and is skilled at it, then she can suck mine all she wants. If she doesn't know how, unless she is willing to take some constructive criticism and learn how, then I would rather masterbate.
Younger women do seem to try harder and are more open to experimentation. Age doesn't really matter though. I get off watching a woman enjoying herself whether it be from oral, fingering, or sex (which I LOVE doing all those). If I get to make a woman cum, then I'm happy. Her wanting to make me cum is a bonus.
