I absolutely disagree with you here. I masturbate every day, often multiple times a day. And it does NOT rob me of sexual energy, in fact I find it's more "use it or lose it", the more sexual pleasure I feel, the more time I make for it, the more I continue to feel. It does not deplete my energy, it recharges me.
If I could be having sex with my soulmate instead, I would, but I can't because he's in prison right now. But even so, masturbation is a major form of self love. It's not "wasting" energy if you do it mindfully and because you truly want to. It's one of the greatest forms of self love and has helped me satisfy my sexual needs without feeling like I need to jump into bed with someone I don't love.
