So yeah. I've got a new girl of a few months, and sex is starting to calm down from the wild rabid sex you always start with, and I don't know if I'm getting bored or whatever. Anyway, bit of background, I used to slut around quite a bit, and I spose I've forgotten what it's like to be with one person? Anyway, I can't cum anymore doing it missionary/her ontop. I need freakier positions. I don't whack off that much, I just get bored doing the usuals. I still like the girl, she floats my boat and everything, I just feel bad asking to fuck her from behind/whatever. I've talked to her about it, she says 'whatever makes you cum hard babe' and smiles, but I still feel bad. Should I be concerned I may be upsetting her by shifting her all over the bed just to get myself off, or just listen to what she says and shut up?
