Nothing vulgar about it, but if I was a busy escort having to read far too many emails, I might skip over yours for others that are a bit more straightforward (“expectations in regards to intimate interaction” is a bit much to quickly respond to). Just a thought, but I suggest as a more clear alternative, something like: “Hi Maxwell. I've admired you on RM. Two things I love the most are kissing and oral. If that works for you I hope we can get together sometime this week. Might you be available at 2:00?” I usually add a bit of information about myself. That kind of message has always gotten me responses.
