37 m had my first sexting experience with a trans female

I have never been into trans or feminine gay guys, they message me often from my posts. They had such a feminine look overall and I actually started getting hard looking at their pics. We actually got along pretty well sexually so it carried on pretty easy between us. We swapped pics and requests and then it thizzled out after a couple hours. I was genuinely aroused the whole time and when it was all said and done I came to s picture of their butthole. I will definitely talk to them again if their down. It could have been a one time feeling, but we shall see
