To my experience acting feminised (without overacting) makes it more socially and mentally acceptable for yourself to suck another gay and be bred but also frequently for the other (top) guy. I also noticed myself, but also my girlfiend and friends that in period that I got bred very frequently I alos behave more feminin withiut doing it on purpose. I also noticed that it when having sex without a condom this effect is even stronger. I am nit a scientis but I am convinced that frequent absorption of semen in your ass interacts with your body. Also I noticed that when I use frequently dildo's and/or get fucked frequently my asshole becomes changes fro being round to a longer shape, more having a slitform.
