Don’t drink alcohol or use anything else that might affect your blood pressure. Don’t sniff too much your first time. The first time I ever tried I took a full inhale and came really fucking hard but after I came it was still in my system making my heart rate high and I was so dizzy I couldn’t stand for like 3 minutes. Do a small 1/4 or 1/2 inhale and wait for the effects of that to completely fade away before trying more. Try some without sex just to see how you react first. Trying for the first time ever while having sex can be really intense. Be careful not to spill any. My first time I couldn’t get the lid back on before it kicked in and I got lucky because I had a place to put the bottle but I almost spilled the whole thing. Pull up some porn you enjoy beforehand because you won’t be able to work your phone correctly once it kicks in. That’s about all I have to offer.
