From my transgender dating experience, boyfriends of trans girls are mostly bi or straight guys. To be honest, apart from the gender they were born as, transgender girls are the same as normal girls. In fact, that is the personal business of transgender girls. They are trans girls, and we cannot deny that there are some differences between trans girls and normal girls, but on a social level, transgender girls are real girls. So, I don't think transgender girls are gay, dating transgender girls never means they are gay. Some transgender girls may look a little bit different from normal girls, they may have a little bit Adam's apple, and some other male features, especially trans girls without transition surgery, but this can never be the reason why you think they are gay.
I've met many guys who are interested in dating tgirls, while they are afraid of being treated as gay if they do that. As a transgender girls, you should tell your dating partners that you are a trans girl, if they are care about your identity and afraid of being considered as gay, never date a trans girl. To be frank, it is not easy to change their misconceptions on transgender girls if they cannot accept transexual people and ts dating from their inner heart. As a cisgender guy who wants to date a trans girl, you should accept your partner from your inner heart firstly. You are so lucky if your dating partner is honest about who she is, because many trans girls just hide the truth that they are trans when dating cisgender guys. According to my personal experience, trans girls who are looking for serious relationship are more honest than others. When they meet their partner for the first time, they will tell their partner that they are trans. I think it is wise to do that. Here I suggest all trans girls to be honest to their dating partners, no matter you are looking for friendship, short-term relationship or long-term relationships.
If you are man who is interested in dating trans girls, don't always care about other people's opinions. Not everyone is really know about transgender people and dating, so most of people cannot understand dating trans girls. Due to these misconceptions on trans girls, it is harder and harder for them to find their dating partners. Never make any statements if you don't know about transsexual dating, or if you don't have any ts dating experiences. Here, I want to mention again, transgender girls are not gay, dating transgender girls never mean you are gay. If you want to meet and date beautiful tgirls, just join an online trans hookup sites, there are many tgirls for you to choose from.
