I cannot and will not have sex with someone who is into labels.
I enjoy sex when the person and I are very much into each other and let things take it's course.
There are some things that don't turn me on or that I'm not interested in trying, but anyone who is so concerned and vocal about "bottom", "top", "verse", "masculine", "feminine", "twink", or "bear" is not the one for me. That is such a turn off.
