I'm 20 and there is this girl I like and every time I hold hands with her or hug her, I get an erection. It's so embarrassing because I don't back my waist away quickly enough and I know she notices. I don't want her thinking that all I think about is sex because I would like a relationship with her but this is embarrassing. If we're walking or talking or something, I'm fine, but if she hugs me or holds my hand for something or whatever, I get turned on and I don't have time to "tuck it away".
What should I do in this kind of situation?
Thanks
