I think it was very tastefully portrayed. After the episode, you could understand it wasn't about getting laid. I was about being with the person you love, trying to make that moment as perfect as possible. There wasn't any nudity, topless, and every character was almost fully clothed (Oh my God, they showed Darren's feet, someone sue Glee -sarcasm-). There wasn't any making out in the bed. They were just looking at each other, and thinking about how much love they felt in that exact moment.
I applaud Glee for showing both scenes, the heterosexual and the homosexual one, trying to make people understand love is love, no matter the gender.
