What does sex feel like on meth?

I fucked a guy recently who was obviously a drug addict (he later said it was meth). He was jittery and fidgety the whole time but a lot of fun and very nice, very cute.. his dick was unfortunately never fully hard, it felt more semi-hard.. but that wasn’t a big deal for me, I was topping anyway (incidentally, his ass felt amazing). Does meth help with sex at all? As in, does it make it feel amazing? Or what does it feel like? I’d absolutely never do drugs, but it got me wondering about how he was feeling.
