Okay so here is my problem.. Sometimes when I have a women at my house and everything is going good, we would be sitting on the couch or bed and starting to get close and I get the feeling like " O ya.. I'm so in"...and BOING!! I will get a ragging hard on within seconds (and we haven't even began kissing or anything, were just close and I know that I'm IN there and the idea of sex gets in my head) So now I'm trying to be smooth and calm while trying to conceal my BONE. And at any minute she could sit on me or place her leg on mine and notice there's a party in my pants, and then GAME OVER. I just get to excited to early.. Any tips on what I should do about this?

Ps. I'm not a sex weirdo.. I guess I just have a good circulation.

Same thing happens when a girl sits on my lap at school or in public... I have to focus like a mad man to keep calm... Is this normal? Do girls like it if they feel a guys getting hard when there sitting on them?? or would they just get creeped out?

i realize this is an old post but maybe you still need an answer or atleast people who come across this will care:

forget concealing, forget avoiding, you have to accept the fact that you get a boner when you get intimate with her and even just touching her + thinking about the next step is an acceptable reason to get hard in my opinion.

it becomes a problem as soon as you try to hide it because from that point on things can go "wrong" when she finds out. but if you realize it and simply accept it as a fact, like "i have a hard-on" without further info attached you can go on as you would with any other fact.
you could neg her, jokingly: "stop dry humping me in public" or something
you could joke about it (very much depending on the situation its happening in, the place etc.)
you could do whatever is the most fun to you.

but dont be apologetic about it, acting that way itself will create the impression to her that there IS something to apologize for.

another light hearted comment that comes to mind since you were wondering if girls 'like' it would be:

"don't take it personal."

i actually think that one is best since it works no matter how she reacts. she could be turned on, then its a neg, she could act all surprised, then it would calm her seeing how easy you take it, and so on.
