Diziness, vertigo during mastrubation.

Hi there, I've been masturbating for the last 10 years. Recently due to work from home I'm masturbating almost every day. Mostly because on I was being occupied and my mind was more diverted on normal days.. but now it seems harder. Now after masturbating, watching porn and getting excited constantly I'm feeling dizzy. I get excited very fast. As soon as I start masturbating I feel dizzy. My legs often feel of sensation. And while I'm gaming I get motion sickness very often. I reduced masturbation like twice  a week but still having this issue while I masturbate. Is that because due to my constant masturbating for a long time my blood pressure increases and having blood flow issues into my brain? How long should I avoid masturbation now? Is it serious?
