My sex drive has been low for many years.

I first started masturbating 8-9 years ago. Back then it felt different. Now it’s just disappointing. I don’t know if it’s the depression or maybe something’s physically wrong with me, but it hasn’t felt the same since. Being “horny” or having an “orgasm” (if you can even call it that), feels different and it happens in different places, and the buildup doesn’t feel the same either. I got my hormones checked and they were all fine and I’m not on any medication. And doing different stuff (edging, touching the g-spot) gives me the same result and/or nothing at all.
