Awkward too shy and very uncomfortable

If you actually told a man that you are neither Lesbian or Bisexual he is going to hear you saying that you are straight and a possibly available partner. I have found that it is best with men that you are not interested in to simply tell them that you are not interested, period. Do not explain anything else, if they continue to pursue you act as if they do not exist. No longer respond in any way to them, walk around them if necessary. If he continues to bother you pull out your cell and start dialing emergency services, I have found that this usually gets them to back off (why I do not know since police have proven to not care about harassment).

If he has stopped talking to you then you have won. Ignore any people that he brings around. Act as if he and they do not exist. If they start to harass you refer to the above advice.

You are 22, start working for a way to support yourself and then move. If it is bad and you cannot live apart from your mother see if she will consider moving someplace else. Sadly this world is run by the men and they have the advantage and sometimes our only choice is to run, I have had to do this.

As an AMAB woman I have been objectified and both seen and used as a fetish object and this bothers me. If you are only interested in transitioned people you are either fetishizing us or you do not view us as who we say we are. I am simply a woman and I only want to be with someone who wants to be with me as me, not because I was assigned male at birth (this is actually a portion of the reason that I live semi-stealth).

Fantasizing about famous people can be fun but the odds of ever really getting together with someone like that are very low.
Also, from experience I have found that in fact age is not just a number and having decades of age difference does interfere with the possible success of a relationship.
