Even tho i'm a girl, i'm going to state my thoughts on this one. I think it would depend on how obese the woman is. If her stomach "hangs" it may be a little harder for a guy to get there unless he lifts it up with his hand, it might be easier if she was laying flat on her back instead of say....having a pillow under her head proping her up....BUT if there is a pillow used under her butt it would probably work out just fine.
