Serious Skin Problem

[helpmeplease11111]

I've had this problem ever since I had sex with a girl a few years ago. And I still have the problems. someone please help me...

I get extremely blotchy red sometimes when I get active or sweat, I never was the type to get red in high school even after a heavy work out.
My face gets super red even when I am not doing anything...
I have these strange bumps that are red on the top of my forehead and on the side of my face near the eyes you can check in the pictures. They get very itchy, but they don't blister or pop when I scratch them... theyre definitely not pimple like. I've always had good hygiene and ive never had problems with pimples... I know the difference between pimples and whatever is going on with my face... I am not allergic to anything, but sometimes my whole body gets red hot and blotchy....
I dont think this is eczema or rosacea because ive never had such problems growing up.

it feels like there are things crawling on my body and my face. I'm thining its a nerve issue... Not sure.. but when I touch the area when its crawling it goes away. I've had tests and doctors say im fine...
