Why does sex exist?

[Ironside]

If you don't think cats do it for pleasure, you have never been around adolescent female cats who are not fixed. Once they find a human male they like, they will sexually assault his hand which is not unlike "getting slimed" from ghostbusters. And they purr the whole time. Unlike my ex wife.

Let me rephrase what I meant. You're chewing viagra while working at the "hot girls gone wild nude bath" (how you got that job is another story). The downside is that you can't "enjoy the benefits" in any way for a week. When you finally get that moment it's gonna be pleassuable indeed, but it will contain way more desperation. More obsession than enjoying the moment.

Another reason to hate cats...

So you're a "hump your leg for dominance and the dick gets stuck for while after, causing him to be dragged around by it" - dog person?

But I'll take pornhub over sex for the physical requirement any day.

Since they did have a article series about it recently in a major Swedish newspaper. That pornhub might cause difficulties to be sexually attracted to someones more normal girlfriend/boyfriend/whatever, due to oversaturation. Dropping the porn for a while should fix it.
No idea if it's your case (I'll assume not), but having intimate relationships without sex, but with an active sex drive is a bit unusual so I was reminded of it.
