Interesting that you should bring this up. I've never really thought about it in terms of how it relates to being trans, but yes, throughout my life I have wondered if I might be mildly (and non-violently) sociopathic. I'm quiet, aloof, can be hard to connect with. This detachment has had a huge impact on relationships in my life, as in who I'm attracted to, who's attracted to me, and the quality of relationships.
Sixteen years post-transition, I can tell you that I have become more emotionally engaged, but only to a point. I'm still very aloof and guarded, especially around people who don't know that I'm a trans woman (which is most people in my life.) From years of involvement in Al-Anon, I have learned to embrace this aspect of who I am in terms of "detach with love" (a 12 step concept.) I don't worry about it, and I don't judge myself for it, but rather I have learned to accept it as a rare virtue.
That being said, I have learned to express crazy love without restraint with my dog (he really is cute!) And I have discovered that sexuality that involves some extreme aspects of BDSM completely short circuits my emotional disconnection and allows me to "let it all hang out" so to speak.
Thank you for bringing this up. I feel excited to discuss this with my spouse and to explore it further for my own joyous expansion... very exciting!
Peace!
