Being effeminate is an amalgamation of being masculine and feminine in a body and generally, we use this word for males who carry the femininity with their masculine personalities. Unfortunately, most people can't understand the practical, biological, and emotional traits of an effeminate person and try to degrade him in every possible way. There is no rule that only homosexual men could be effeminate. You can find many straight men whose behavioral patterns, postures, and gestures resemble the typical norms of femininity.
Keeping that aside, the effeminate males of different age patterns are always considered delicate, fragile, sensitive, calm going and effortless. You can use all the soft adjectives to describe effeminate men, but this is the very reason why people take them for granted and find opportunities to demean them. There's this microaggression thrown at every effeminate guy by the people around by considering them as the girl in a queer relationship. Though it's fine for many, in the end, it dilutes a person's personality.
Moreover, society always acts hard on every effeminate man and when he comes out as gay and he gets into a relationship with another man, he expects his partner to respect, value, understand and support him and his personality without throwing judgmental criticism. So, if you are a person who loves to be in a relationship with an effeminate gay, you must know a few basic things to understand and get along with him!
