I’m thinking that there is the same tendancy for lots of us. Think about it, the vagina is built to make us cum-so soft, velvety, warm and slippery. The mouth is built for tearing up food. Think about the difference between saliva and pussy juice. Big difference.
I can cum orally, but it takes longer. If your woman is a good sport, have her experiment around. Some of this may sound a bit odd, but try it, you will like it. My girl kisses and sucks my balls-very gently, and even puts them one at a time in her mouth. It’s a very different feeling, but i can watch my dick really puff up when she does that.
Then she licks it and gets it nice and wet, then holds her lips tightly closed and then slowly forces my dickhead into her mouth. She continues the tight lips and goes down as far as she can. She also will very gently bite into it, or let her teeth lightly drag as she goes up and down. Sometimes she will bite into the groove just behind the head, and suck very hard on just the head. Makes it grow like a mushroom.
When her jaw gets too tired, then she will lick/suck all along the bottom side, concentrating on that hot spot (frenulum?) This keeps you stimulated while giving her a break so she can last til you cum.
Visual is a big deal with oral sex for me. It’s better than anyone’s porno. I love to watch her lips as they consume the head. There’s just something special about watching a girl do oral on you. Always make sure her hair is pulled back and you are both at a good angle so you can watch the show.
Anyway, these are some of the things that get me off. Give ‘em a try. Hell, if you can’t cum, just relax, enjoy the show, then fuck her hard and cum the easy way.
