I might have lost my interest in sex

Hello! I've been trying nofap for 2 years, and now I've finally kind of "succeeded" with 223 days streak. I don't see many benefits from my streak anymore, but I don't want to do any PMO, so I think I'm just going to stick with my current streak.

Anyways, I'm 18 and virgin, and I think I have lost my interest in sex. I've been feeling this way for months already. Otherwise I would be completely fine with it, but I've been reading stuff in the web telling that you should have sexual contact when your brain is still growing and that virginity can cause problems later in life. Are there any truth in those claims?

It's not like that I'm afraid of having sex or that I hate it. It's more like it doesn't just interest me, since I don't feel like I should use my time dating or trying to get laid. Back when I was still heavily addicted I thought nothing would be as great as having sex, but now that I've mostly rebooted I've noticed that there's many things that make me happy and that I consider worth investing time in.

So, I'd like to ask if it's mandatory for my physical and mental health to have sex at young age?

 

Sometimes, I'd say about once or twice in a month.
