I don't know how and why the moment I'll smoke let's say like first 3-4 puff, I'll start leaking sperm and my dick will shrink to a tiny clit! What's the reason behind this?

Apart from that I'll be feeling feminine and the more I'll smoke, I'll feel like my nipples are twitching and it's so super sensitive!

To give one perfect scenario, just now before writing this, I started to smoke after 5-6 days! After my first 3-4 puff I felt my dick has shrunk and I'm leaking! As it's already something that im very used to, I continue to smoke another few more puffs while sitting at the same position. PROBLEM HAPPENS WHEN ILL START MOVING AFTER SMOKING Ex- I just got up as I wanted to do something, but the moment I'll move from the beginning position, I'll leak cum massively as if I have came. But yes it's only cum, not orgasm. Pls do help me explain this unbearable shit
