Intake, my man, you are a guy. This is so NORMAL... You are a heterosexual man. Dont be ashamed, we are like animals, who need it 24/7.. There is nothing wrong with it.. make sure she gets the idea that its because she makes you feel that way, that she is special... do not let her know that you are horny in general, make her think its just her that does it for you, and she will feel great about it, and probably be turned on by it. If she thinks anything with legs turns you on, she will be disgusted.
