I don't know the right answer to this question because I'm ignorant when it comes to all religions. I think it would really suck to not live your life as your true self and deny yourself happiness for some after this life " paradise " that may be and most likely is a myth. Maybe you should just be a good person and find your happiness while you're here then.
If you are gay and Muslim and you follow the religion how you should and do not act upon your homosexuality. However you pray and treat them right, if you get to paradise will you be able to be gay or can you be turned straight?
I think the biggest problem would be to find 72 virgins for any gay jihadists who died defending the faith.
For an accurate answer to your question you should talk to Imam.
