You don’t say why you don’t want to date/shag a Trans man. What lies behind your statement is your key to answering this question.

Say, for instance, you liked someone’s look, and swiped right. Later, you looked further, and saw that the guy is short; well under 6 feet tall. And you have a vehement dislike of anyone under 6 feet tall. Fair enough?

Similar scenario; you like his look. But in this case you read something in the profile that indicates the guy’s ethnicity, and because you have had bad experiences with other people of his ethnicity, you decide to swipe left. Is prejudice at work?

Do you have a prejudiced opinion of Trans people in general, that leads you to dismiss these guys who you’ve found attractive, without giving yourself a chance to meet them? Are you sexually disinterested in the concept of Trans men? Would you meet these guys if they were cisgendered men?

There may be some overlapping going on here. There may be a combination of preference, disinterest, fear of the unknown. Again, only you could answer this.
