I recently visited a TS as a first timer like yourself, I'm very attracted to women and not men but have always been curious to try with a TS having watched lots of tranny porn.
The TS I visited was 'Trans Sofia UK' on adultwork. Incredible body, very feminine. From the minute I arrived and we started undressing one another I was in my element, and holding another persons hard cock for the first time was a real turn on, the second I started sucking it was a great experience, I was so turned on I let Sofia fuck me but it was too painful even with a good amount of lube. I enjoyed fucking her ass and wanking her cock at fhe same time, I still get a hard on thinking about the whole punt weeks later!
To the OP, give it a go you won't regret it.
