This might not be the right place to post this, but I'm new to online dating. I'm bisexual and have been chatting to a woman who I plan to meet up with. I'm not comfortable with dating a trans woman, so would prefer to know beforehand if someone is trans. I have asked her if she is biologically female- she hasn't seen the message yet but I'm now worried that this question could potentially be offensive. Am I ok to have asked? I know I wouldn't mind being asked...
