There has never been a massive uh oh boner moment for me, what i will divulge is that i can't control the danm thing when i'm with my girlfriend, umm i guess she turns me on too much... Even if i just think about her and memories of when i'm with her and what we've shared, can make me erect. On the walk home today infact, my mind was wandering and what do ya know, but jeans hold it in and i just tuck it up the waist band and have done for years before superbad told me too.
