I really love getting totally naked with an equally naked woman and slathering baby oil all over ourselves - really loads of it - and then rubbing our bodies together for ages. It is just such an erotic experience. Sadly, not too many offer it, but I will always make the effort to see those who do. Bjanee of Bristol does it wonderfully well. Some do it on a plastic sheet, some on rubber, and the most recent experience I had was on an extra thick blanket which was obviously destined for the washing machine at the end of it.
It's true that baby oil and condoms don't go well together. But sometimes I'm happy with a session that doesn't include penetration. Or if I want penetration, both parties can go and shower together, which is good fun in itself, and then break out the condom. One thing to be careful of, though, is that if the soles of your feet have got oil on them, you can easily break your neck by slipping as you get into the shower.
I also enjoy seeing transexuals, and two cocks slithering around together is a hell of a turn-on. Not everyone's taste, I know, but there you go.
I've tried nuru massage but I think it is over rated and a lot of fuss about not very much. The nuru gunk they use costs an arm and a leg so it doesn't get splashed on with wild abandon, the way you can with baby oil.
