Any thoughts on how to keep him harder and how to just generally make this better for me? I've never liked being on top...I guess I could try masturbating that way more often, but it just seems to be murder on my legs and it is so frustrating that I usually end up crying. He likes to stimulate my nipples but it's like they just go numb in this position and it's not terribly pleasurable. Maybe a cock ring? I dunno. Help!
Some physical info, in case it helps.
Him: Late 40s, normal weight, runs 5 or 6 days a week. No health problems he knows of.
Me: 35, overweight, cycle 5 or 6 days a week, Pilates five days a week. Mild arthritis and tendonitis in right hip. (My discomfort during sex is very symmetrical between my left and right legs, so I don't think the arthritis is what's causing the problem although it's probably not helping, either!)
