None of them. I'd rather live alone than put up with any of their bullshit.
Living alone is the way to go. If you want sex, buy it. It's so much easier. I would have no problem living in a 1 bedroom condo overlooking the ocean. Pick up the phone, call in a little Asian massage girl, give her a few hundred and have your fun, then out the door she goes.
Or go down to the beach boardwalk on a Saturday night and pick one of the young hotties strutting their shit on the boardwalk and bring her up to your place. A fat joint and maybe a line or two and some drinks and she's all yours.
Again, when your done, she's gone. Just cover your stump, before you hump.
