Writing from a bunch of different perspectives is great, and absolutely something everyone should do when they start out. It's a great way to find out what you truly enjoy playing, what works for you, what makes you stick with an RP the longest. I'll play both sexes, but there are certain types of characters I won't touch because I don't like writing exclusively from their point of view. Wouldn't you rather RP with someone who's writing a character they can play for years and years VS something they won't be as interested in a few weeks down the line?
