Okay, here's how it went for me:
I'm bisexual. I've always been bisexual. I only completely realized this for the first time when I took MDMA for the first time. I could look back into my past at that point and pinpoint homosexual feelings that I'd had early on, and finally see them for what they were and completely accept them. At the time I originally felt those feelings, I had just shrugged them off as products of a healthy and mildly overzealous imagination.
MDMA allows you to peer into your subconscious and see what existed all along, perhaps hidden from introspection due to some level of repression, kind of like peering through a window into your own soul. This is why Dr. Alexander Shulgin's original idea for a colloquial nickname for MDMA was, in fact, Window.
It is possible for people who self-identify as "straight" to have homosexual experiences on MDMA, while still being "straight" while sober. MDMA can open up your thought processes to novel and new experiences that your inhibitions and natural sexual desires keep you from wanting when you are baseline. Sometimes these homosexual desires on MDMA are because, while sober, you have repressed these hidden feelings and MDMA is simply allowing them to flourish, which is what happened to me.
Sometimes, it's simply a product of inhibition-less ecstasy; you feel such a heavy, thunderous amount of love for everyone and all things, comparitively little minutiae like your sexual orientation can't hope to stand in the way of your need to fulfill this love. Once sober again, that person usually no longer feels these feelings, and is, in fact, "straight." There's nothing wrong with feeling this way on MDMA. You can still be straight and have homosexual experiences, especially on MDMA. Consider it experimentation, really.
Basically you're saying people who did not realize their bisexuality/homosexuality, mdma allowed them to be open towards these feelings.
