right on, g/f! but you'll need some kind of stabalizers. i use those for deep, stretching sit-ups. you'll roll all around to keep your ballance...especially if you getting pounded.
personally i want the swing. but if that's you in your avatar, whatever position you want is o.k. with me.

...if i wasn't married.
actually, i have tons of ideas on sex. i'm a total addict...if any guy isn't, i suppose. pm if you need any ideas for a special night.
