He dated Jenna for around 4 years, and Ellie only 18 months, and during that time some pictures with Brandon came out. (He met Brandon while he was with Ellie) Some gay men have been married to women for decades, and have had children. Of course he can be bisexual, but I also think he can be gay. He also developed a beautiful friendship with Elton John, and stated in some interviews that they got to know each other deeply. I really think Elton helped him a lot to embrace his true sexuality.
The other day I posted a Instagram capture where everybody were interacting. Jenna posted, Ellie commented, and Richard and Froy liked. That means that they're all friends, that they all know each other, and that two women who dated the same man are friends ... come on!, That only happens when the man is queer!
