To be honest, that is the one real downside of the doll; with an actual woman, you can have standing sex, and it may not be the easiest thing in the world, but you have SOME help with holding her weight up. with this, not quite so much. However, you'll find she's useful for posing on a surface like a table or countertop, in addition to a bed, couch, etc.
Sorry, not accepting trades at this time; (I'll take $100-200 off if you have a Nightmare in the Dark MVS cart to trade, though) I need the money at this point, bad economy, travelling, blah blah blah. I already have a woman, anyhow, and bought the doll to get away from all that "cuddling after sex" shit.
However, would consider partial trade if she has cooking skills, is mute, and comes with a year's supply of birth control.
