An ex-gf is the only one I'm completely open with about liking TS. I started well after her and I broke up amicably, and she's my closest friend. We've discussed anal, giving oral (bj only, she's not into other girls) and even comparing largest cock size of partners. Since I was with her in the past, and have no allusions about myself, I knew I was not going to be her pick for largest cock.
I however, had more variety with white, latin, asian and bi-racial, but she still took the win. Can't say I'm too disappointed either.
