Sex In My Head…always
Man I am with you. I'm pretty sure I'm a sex addict and that it's an unhealthy over use of sex and fantasy. Sad to say I don't want to stop and don't expect to stop any time soon.
I am very aware of the dangers of stds and never have sex with a stranger but it's sure crossed my mind a hundred times.
I identify as straight and have been married twice. My current wife of a dozen years is a trans girl and I appreciate mostly all aspects of sex with an appropriate partner.
These days with a certain amount of ED, I do find I fantasize more about sucking cock and rimming than I do about fucking anyone. And I love being rimmed but have never gotten a thrill from being fucked myself. Only tried a couple of times but probably not for me.
I do however find I enjoy using my mouth and tongue on my wife and especially love to rim her sweet little tush.
I think what you describe is very common in most men. I know it is for me.
