Painted fingernails, coincidence?

I’ve never heard anyone relate a personal experience of poppers and anal sex. Anything that interferes with the feeling wouldn’t work for us. Maybe for first timers it makes sense but I’m curious if it relaxes the sphincter as claimed.

I think the hypothesis is close but not directly correlated. I think that a woman who truly enjoys anal and gets it regularly will feel ultra feminine. With the constant flow of dopamine, serotonin, and oxytocin running through her brain. Therefore she will be more likely to engage in feminine habits.
