Could this be latent that i'm encountering, please advise?

since teenage, somewhere ard the puberty age of 14 (i'm age 25 now) i get spontaneous from the sight of female bodybuilders (did felt guilty & ashamed at the time), straight did gave me back then, but eventually i surfed for female bodybuilders site, began to it almost 98% of the time daily(in the absence of straight ). this went on well for the next couple of yrs untill now, so much so i met a gal and couldnt do her, eventually left me no choice but to walk away frm her, because i couldnt perform. i tried to validate my uality, i tried watching straight again & tried to , once in a while i do get a frm it, but most of the time, willy just wouldnt perform. I've tried gay and no arousal or of what so ever, one might equate masculine female to a feminine dude, well i can say that didnt do for me, i've never once or fantasized a dude or fxking one. i went to the doc, did some blood test, he said i was alright, the hormone is still good, and nothing wrong with me physicaly, since i still get morning wood, all he could give was that its all in my head (depression). if any one out there is having the same prob, please advise, i'm really running out of numbers, i really dont know what to do anymore, am i repressing my ual thoughts or was it the depresion, or would it be that i'm perfectly normal having an taste for masculine females. please help, please advise
