gay guys usually like masculine features, not many go for feminine looking trans women. This is what my father told me anyway.
Hello, they are not women! They are men dressed in womens clothes, some have falsies, but they are still blokes. Nothin against gays, just not my thing.
As for what they like or dislike, you might observe from this website we all have different tastes, I am sure gays are also as varied in their taste as straights. Usually there will be one who likes to give and another who likes to receive in every gay relationsship at least.
