If you are into the feeling of anal penetration, like I am, then it feels amazing. Some people don't like that feeling. I get rock hard and can cum just from anal stimulation so honestly I almost prefer getting fuck in the ass whether with a real cock, dildo or vibrator and with a girl, transgirl or guy.
As for the age old "does this make me gay?" question...my answer is who cares?? It's just societal labels. You are what you are. But if I had to answer, I'd say being gay is an emotional issue. Do you exclusively want to have emotional relationships (take sex out of the equation) with other men? No women, no trans, just men. If your answer is yes, then you are gay. Otherwise not.
