man to man massage

I am bi-curious and I am going for my first man on man massage. I have talked to the masseuse and he said we would both be nude and mutual touching is allowed. what do I do first?

I think I would start by undressing and lying face down on the massage table, bed or floor, whichever he's using for the massage. Let him start a regular massage and see where things progress from there. I assume there are no upfront expectations on his part. Just enjoy the massage and I'm sure you will be feeling relaxed and uninhibited before long. Then if you feel like grabbing his dick you won't be so hesitant.
