I think the belt has drastically changed my view on sex and masturbation. Before I had to wear it, masturbation felt like something that is a given thing that has to stay a secret. It changes to something I can't have anymore and that is since then a regular part of my thoughts. It definitely makes me think more about sex then less.
I think much more drastically is the difference in my views on sex in a relationship compared to unbelted people, but because I never was in a relationship before I was belted it's not really a change in my behaviour then a difference. I have learned how good it feels to give your partner a great orgasm if you know you can't receive anything similar in return. You can be completely unselfish and only focus on your partner. It's very satisfying for me to know how good I was for him and just for him.
I think this is something an unbelted person can't understand but you need the "right" partner for this. Someone who can still enjoy it, even if he/she can't give the same to you in return. It's nice when they feel sorry for you overall, but it should not impact there feelings to much during play time.
