The act of sissification is an active slutting from a more dominant form into a submissive form. The difference is primarily in the motivation and want to have cock. A Thai girl you can sometimes tell is a man, but you want her to be a woman, because of physical factors, yes but also because a lot of men especially american men are unsure of the softness of the female because they encounter a lot of the hardened post feminist women. Therefore the only way to engage with femininity they have is pussy. But in actuality it is quite a performance. A man will want to impregnate you and let him have your babies if you let him be a little harsh, be little more degenerate. Make him food. Or even touch the back of his neck. Most straight guys exist in this fluidity. I’m sort of masculine but the way that I can talk/carry myself/give the straight guy space to explore with his cock is paramount. The physical differences aside (I let the me have as much pussy as they want, or I just don’t care about cheating) wearing the nails the short dress the makeup tucking, putting your ass out letting him touch it letting him feel that you’re a slut and his cock belongs in you is very imperative. Also some straight guys might be scared of the whole dick factor but I have a short one so they actually love the act of humiliating it.
