Nah it's normal. If she's a friend, you value her and probably for reasons that you might value a sexual partner even if you're not thinking about her for that. I mean the difference between a friend of a gender you're not interested in vs. a friend of a gender you are interested in vs. someone you are actually romantically interested in can be nebulous to the point of being almost non-existent. But there are differences, and you will come to recognize those differences as you get older and I can't tell you how that will be for you because you're your own person and you'll develop in your own way and this **** is ****ing complicated.

But for right now just accept that jealousy is not a personal failing on your part. You want someone's attention and a social situation is making that complicated. It might be that you want that person's romantic attention and don't want them to give that to anyone else or it might be that you just want that person's attention in general as validation (everyone needs validation) and are insecure that this person will be able to dole out attention while also having a romantic partner.

Nothing about this is simple or easy or given to easy intuition. Unless you're a secret creep, and I don't think you are, you'll get the hang of it in at least one or two or three decades.

For sure

I’m just saying it’s best kept in check

Nature isn’t always your friend

I’ve found if you have anal sex with a woman you maintain that cherished feeling of ownership even if she’s with another man.

It's tighter.

And a statement of dominance.

Do you subscribe to the belief that everything in life is about sex. Except sex. Sex is about power.

No. If “sex” is about power it’s not sex it’s rape and rape is violence not sex.

I've never heard anyone combat that ideology that way. Interesting way of putting it.

I thought of it while I was raping elph.

Pics or it didn't happen.
