@Joshb from a best use of time perspective, you might want to schedule an appointment with Mark; his RM ad states that he is moving to Europe for 6 months, so if your schedule match, I think that would be a good investment of your time and funds to see him before he goes; here's a link to his RM ad:

I saw him a few years ago and thoroughly enjoyed my experience.
Alex will give you a great massage, but I think there will be less opportunities for as sensual an experience as you would have with Mark.
I'd be tempted to try tpmscl33 also; he is also know as T_Wilcox; here's his RM ad:

it looks like you'd have a sensual massage experience with him, too
let us know what you decide to do!
