I 150% prefer a couple of 2+ hour sessions to a dozen 1-hour ones. An hour flies by fast, and it doesn't give me the time to properly create an immersive and bonding experience. It makes me feel rushed. This especially pertains to more involved and time-consuming sessions like medical fetish, bondage, and full feminization. It also avoids burnout for me. I'd rather deal with a single person for three hours than three different people in three hours.
