Dreams2014,
We're kinda the opposite actually. When I get horny I get very frustrated with my body. My libido only reinforces the disconnect.
Honestly, I do enjoy the sensation of being inside a vagina but I can't say I'd miss it all that much. (I haven't started HRT either.) I get anxiety whenever my genitals are involved. Sex would be more enjoyable if I didn't have this damn thing.
But everyone is different.
I think of gender identity like this: Your identity is not one entity, but rather made up of many parts. Your gender may differ from part to part. In some areas you may be more masculine, while in other areas your femininity may be dominant. These opposing gender identities manifest in our lives in different situations where different parts of our identities come forth and play a central role in how we interact with people, problems, the world, etc. This is why I think some transpeople experience feeling "male" in some situations and "female" in others. Some people would identify as being completely male or female, while others might consider themselves about 50/50. Then there are people like you and me who are predominantly feminine but have masculine aspects to our personalities, which in my case has made me able to present as male all my life with little difficulty. Unfortunately in my case sex is not one of my masculine areas; I have very little male instinct to penetrate. It's very possible that you are predominantly feminine except where related to sex.
I have no idea if any of this is true or not. It's just the way I try to make sense of myself.
