I'm a man in my early thirties who as been without porn or masturbation for a little over two weeks now (my wife and I had sex once in that period of time). It's going well in terms of avoiding temptation, but I haven't had a recovery of my libido (spontaneous or longer lasting erections).
However, I have one particular unusual sexual fantasy/fetish that particularly turns me on (it just popped into my head today for really the first time), and it almost instantly gave me an erection. It is one fantasy that I'm bothered by (it's not anything illegal I feel I need to add), though, and I want to get rid of (ideally, I don't want to have to rely on any fantasy when making love, but I don't know whether that is realistic). I'm somewhat worried because I've been using this particularly fantasy regularly for the last three years or so, and it's much easier to get off with it (to the point it's hard for me to get off even with other sexual fantasies I used to regularly use). My hope is to get rid of fantasy altogether, but I'm worried that I'm so hung up on this one that I will not be able to overcome it and eventually get aroused normally again.
Is it possible to overcome this and return to normal sexual appetites?
