feel wrong after masturbation

It's most likely guilt to be honest. After all, 'nice', 'normal' people don't masturbate at all - and certainly not over TS porn - or at least they don't admit to it And what if your family found out? Or your friends? Or...

Of course, it's nothing to be ashamed of. People like all sort of sexy stuff. If you knew what they were getting off over then you would most likely be even more surprised.

Oh, and as for 'porn-escalation' don't be concerned about that either as, as far as I can gather, it doesn't exist. I quote:

Another one of the claims made...is that internet pornography use causes a change in sexual preferences described...as, “escalation to bizarre porn.” This is an oft-repeated statement by the anti-pornography movement. It’s been repeated so many times over the years that people have started to believe that it’s true. It simply isn’t – there is NO empirical evidence to support this claim. And besides, what’s wrong with “bizarre porn,” as long as everyone in it is consenting and it’s ethically produced?
