I am the biggest sucker for a good romantic anime/manga/story. Especially romantic comedy.
Guys and girls have been known to fall in love from time to time, so it's really not all that surprising that both sexes would enjoy a good romantic story. Similarly, I know plenty of girls who love to watch crap blow to pieces... so of course they're going to gravitate towards some of the action series.
In in the end, it really just comes down to what you like. Don't make excuses for the things that make you happy to those who would judge you for it. If it makes you happy, then that's all that matters. Those who judge others, will also judge themselves. Pity them, for they will never know true happiness as a result of their own self-imposed limitations.
