For me, it's not knowing who's gay and who isn't!!! I was at my college doing some paper work and I saw so many hot dudes! The point is, I'm shy and I don't have a good gaydar.
Same as you. It just seems so hard to get a boyfriend.
Like. First of all you have to find someone who's gay, which is extremely difficult when you're shy. Then you, of course, have to get feelings for the person. Then the last obstacle, which would be for him to actually like you. So many impediments.
Dealing with or witnessing other gays who do stupid things to enforce stereotypes... like lying about HIV or STD status... or gays that walk around looking like they've having an identity crisis, hitting on straight guys and being overall obnoxious.
I'm shy and introvert and it's very hard for me to open up to people. Sometimes there are people who want to be my boyfriend but I have to decline since it's very hard to find faithful one.
All in all, it's very difficult to find someone faithful to be my boyfriend
High school
Coming out
Getting bashed on the street for your sexual orientation
Getting told by Christian extremists that you're unnatural and that you're going to hell
Death threats
Homophobic slurs
Dealing with homophobic family members while you're still in the closet
And at the very bottom of my list... Trying to find out whether the guy you like is gay or not
But that's just from my experiences and point of view :)
