I am a male just short of 22. I have masturbated regularly (approximately once every 1 or 2 weeks) for about 7 years or so, and had been trying to curb my habit for the last 3 of those. About one year ago, I had nearly stopped doing it for a prolonged period of time (just allowed myself nocturnal emissions), but one day I somehow stumbled across some photographs of some really gorgeous pre-op transsexuals. More or less since then, I have been amassing downloaded images of really attractive pre-op transsexuals. However, because of this, my masturbation picked back up, and has been more frequent than ever of late. There have been times where I would do it more than once per day for several days in a row.
Now for the question. I am not worried about whether this is wrong or socially acceptable or anything, but I am wondering if this is an unhealthy fixation. Although I still consider myself to be attracted to women, it seems lately as though I am only truly aroused by really gorgeous pre-op transsexuals, and it is often all I will look at while masturbating (as opposed to mixing in women as well). Basically, I am wondering if this could become unhealthy by my setting unrealistic expectations. If I get to the point that only these really beautiful transsexuals are arousing me, I am concerned that my sexual expectations may be skewed and thus negatively affected (since I assume the actual number of really beautiful transsexuals to be much lower out in the pool of singles, and most of them do not really desire to keep their male genitals forever). Is it possible this could adversely affect my sexual health, and if so, is it even possible to grow my sexual attraction?
