The short answer to your question is yes. Castration will definitely end any interest in masturbation, as well as really ruin your life. Seriously, there are a few possibilities, assuming that your sex drive is so strong. First, see a doctor about it. There are medical solutions which can help. Consider marriage. I had a good friend who got married and that ended his problem with masturbation (6 times a day). His wife had a hard time keeping up with him, though. Consider counselling. A trained counsellor can sometimes help you get your head straight. As they say, sex is 90% in your brain. I realize this is a real problem and these are general answers, but they have worked for others.

How often do you masturbate? Why do you become depressed afterwards? Why do you feel disgusting?

I am female. I discovered masturbation, and from that point on I pretty much masturbated every single night for eight years. I had to pull back a little when I got to college as I only had showers to bathe in.

I certainly don't think it has ruined my life in any way. I feel proud that I know how my body works and what makes me feel good.

oh it shouldnt make you feel that way!? its normal and not anything to be ashamed of or depressed about
