Don't live in Montreal so everything is outcall for me. But even when I'm at home, I always do hotel outcall. In between regular relationships and SPs, I've always associated hotels with memorable sex.
Plus, when you stay at a home you totally lose the threat of someone else walking into your room while you're getting it on. It's happened to me two different times and each time, my lady friend and I got a great laugh from it. Since they expected the room to be empty, there was no knock either time. The cleaning lady caught a lady and I in cowgirl the first time. The second time was the business lady rolling in her suitcase, only to freeze when she saw us lying there. She apologized once and ran out of there while we laughed heartily. A few minutes later, the room phone rang-- but we didn't pick it up because we were busy again.
