Will ditto that Tristan is fantastic. Absolutely fantastic massage, dedicated room in newer apt complex, and rocking body. Very reasonable price too - I always go for the 90 mins because it's just another $20.
I've also seen (and recommend) the following:
Trevor https://www.masseurfinder.com/members/handsoftime.shtml met him when he did 4 hand with Jeremy (who's now in Ft. Lauderdale) and have seen him 2-3 times solo. Super nice, real good massage, some playfulness. Only available in evenings and weekends. Nice apt.
Grey https://www.masseurfinder.com/members/magical_touch.shtml nice guy, nice setup in upstairs room, good massage, playful
Zach https://www.masseurfinder.com/members/dallaszach.shtml nice place, gated parking, uses bed which I generally don't like but he makes it work, rocking body, good conversation, more limited availability (evenings, not weekends), playful, far north dallas location (Arapaho/Tollway)
Chris https://www.masseurfinder.com/members/cstud87.shtml gated parking, nice setup, better the more times I've seen him, flexible scheduling, northern most location (near Bush/Tollway)
I've seen others (I guess I like sampling what Dallas has to offer) but these are the ones I go back to.
