I liked the scene where Grace gave him the BJ too. I was like "FINALLY, a woman who actually gets it!!" I thought that most of Max's romantic interactions were respectful in that way - like with Billie and Tom. Even Jenny was doing her best to be supportive even though she decided she could only be with a woman in the end. It was handled very well imo.
But I did have issues with how he got T. When I saw it the first time, it made it all seem very "underground" - it sort of worked to demonize transition in a way, even though he got on the proper, monitored dosage later on in the series. They should have introduced legal methods earlier on, because that sort of image sticks in people's minds and even after you correct it, they still envision that.
I can see why he was on The L Word, given that he was a lesbian pre-transition, but they could have used a lesbian MTF on there. That would have been even better, because they didn't even touch that at all. Well, there was Lisa, but don't get me started on that...
