Don't try to be someone you are not. Because you are the best person when you are you. Just stay as you are and you'll attract the right trans woman. Just talk to her. Go and tell about yourself and try to know that. That's it.
Body language
Body language is a common trait which will determine your confidence level and the future thing that is going to happen between you two. Body language must be good enough so that you look good enough to represent yourself as a complete person who is worth dating or being in a relationship. Sit comfortably, walk with a good posture and try to make contact and have a smile on your face. Try to talk about healthy topics in which you and your trans dating partner both can respond. If you have confidence in you your body language shows that and hence it gives a positive impression about you.
You are more than you think
Yes you are. You are more confident, smart and a attractive person than you think you are. All you got to do while meeting a trans person is just be yourself. Show them the best side of you. Specially transgender woman love the guys who care for them. Who can show them what love is and how happy they can be with them. Just show simpler acts of kindness and well manners. Do simple and happy things with them. They will be impressed naturally. Do not try to over do anything. That can ruin the scenario. And always remember you are not going to impress anyone in a day for lifetime, if you are looking for a long thing you will be judged for a longer time. So do not try to.imitate anyone just be yourself. That works magic. Period.
Believe in yourself. Take the necessary steps for your improvement. Gradually you will develop habits in yourself that will make you a better person for them and they will love you more.
Speak Confidently
Speak with all your heart. Do not try to show your over confidence or do not show your nervous even if you are. He or she will not beat you up for anything. Trans woman or man or just like any other common person. Just speak with confidence. High head and eye contact while talking can impress anyone.
Playful touching
Just a simple handshake or a greeting hug kind of a thing is always allowed if you are looking like a decent person who knows how to behave but do not rush for anything if you feel your partner will not be comfortable if you do something like that. Trans people do not get so open to anyone really soon. They need time to understand and trust other person.
The thing here to learn to attract or impress someone you got to be yourself no matter what. You have to be satisfied with who you are. You should be able to love yourself. You do not need to be anyone else to impress anyone. And if you can be yourself trans women will love you.
