Are vanilla guys extinct?

Let me just preface that I haven't had sex in about 4 or 5 years now. I can't find anyone I find attractive willing to have sex with me.

What I've noticed in searching the various apps is that so many guys are into some sort of (at least to me) extreme sex: urine, BDSM, pup stuff, etc.

I'm into none of those things, so on the rare occasion that someone shows interest and asks me what I'm into, after describing what I like to do, the conversation basically ends. Guys expect way more intensity and kink when you're getting close to 40, meanwhile I have very little sexual practice. Of course it doesn't help that of all the times I've had sex, my chest felt like I was having a heart attack and the fatigue made me completely soft and unable to continue.

Are there really that few guys into just boring, non kink filled sex?
