In the past few years I've seen a strange trend in character designs which focuses more on their race and/or gender than the character's actual personality. Some creators go farther to also make their sexuality a prominent aspect of their "character". As a DM and D&D player I've run into individuals who make the usual mistake of taking these traits and using them as the only methods to express their characters, and that is utterly disappointing. A good example is someone who plays a gay character, and proceeds to consistently bring up the fact that they are gay instead of expressing an actual element of their characters personality. Or a female character who consistently flaunts the fact of being a female instead of saying something which tells their compatriots about the character. It comes across as banal and in most cases silly, and while it can be funny in some instances the majority of these occasions just become awkward to work around (especially as a DM trying to build a story around the characters and their particular personalities). In my opinion a character is best defined by their personality and their actions, their race, gender, and sexuality are simply ornamental aspects which add to that personality. So for example a rough and tough paladin with a scraggly beard who acts jovially with his friends and tenacious in combat, could walk up and kiss his male lover after a long absence, and the party may be taken aback at first, but will get used to it. This type of measured reveal and the use of subtle storytelling is far more interesting to me. Bashing everyone over the head with your character screaming "I'M GAY!" throughout the ENTIRE campaign will do nothing but annoy people and break their immersion (which makes each meet up less enjoyable until the group starts to leave one-by-one).
Now to clarify I have no issue whatsoever with just about any character someone could bring to a party, as long as they aren't created in a way which adversely effects the party or is utterly abstract in comparison to the setting they are fine. So a gay, female, or purple person are perfectly fine. The core of any character is their personality and their actions everything else is secondary. An excellent example of well written characters (though some are certainly jaded) are those of the Berserk series. Every character is defined by more than their gender, sexuality or their race, with few exceptions. Honestly Casca's annoying phase in the first half of the series (thus far) is the only glaring exception.
So when creating a character keep this in mind. Your characters personality will influence how they speak, and their actions frame their image in other characters minds. If your framing is weak and you only talk about your characters race, gender, or sexuality other characters will only ever think of you in those terms.
