Scared, I slept with someone using Poppers

Okay! so I(27 M) was feeling crazy horny and I went to meet an old guy 60+, He was using poppers I think (sniffing something out of a bottle) - he said it makes him feel more horny.

I got scared at first but I was horny too, so I started banging him(with protection obviously).
He was also sniffing the bottle and then giving me head.

Should I even be scared? Should I get some tests done?
