feel wrong after masturbation

[bonobobo]

hey guys, so generally I find shemales really attractive and love to watch shemale porn. I fantasize about shemales, too. But, after I masturbate to shemale porn, I always feel disgusted and wrong for an hour or so... before I go back to liking shemales again.

So, I wasn't sure if I was actually attracted to shemales or if it was just a porn-escalation thing, so I didn't watch porn or masturbate for 3 weeks. I found my desires for shemales (and females too) were just as strong after 3 weeks... so I guess it's innate? But if so, why do I feel bad afterwards?

What I would like help with is to know your experiences with this. I don't want to feel like I'm doing something wrong after masturbating to shemales so why do I?
