I feel disgusted with myself and ashamed

This is a throw away for hopefully obvious reasons.

So a few days ago I got a boob job done, and at first I felt surprisingly well, mostly numbness and not much pain, basically everything is going well which is really nice. After I decided to take my first shower post op I wanted to take a look at the mirror to see how it looks and how bigger my boobs are now.

After taking a long 10 seconds of looking at myself I noticed I actually started getting an erection, I felt so fucking disgusted with myself, after all this time I've been living socially as a woman, living my life and doing pretty well for myself I felt like what I was doing was just a sick fetish.

I'm just sitting at home and just can't stop thinking, what the actual fuck is wrong with me.

I just feel so fucking disgusting and sick just by thinking about it.
