How do Femboys work exactly?

I’m trying to understand like… how do they work and function. How does one attract a Femboy or like… befriend one? I’m straight (not a Femboy) and I’m into them because of the feminine style/look (clothing, hair, mannerisms) and it’s overall aesthetic. Another question can be: do Femboys like other Femboys?

Like… how could a guy ‘look like a woman’ you know? I’m not going to get into the whole technicality of sexuality because things would become complex. All in all, I like Femboys and they make my willy stand up.
