Welcome to Gaia! ::

You don't sound weird to me. Don't worry about it too much.

Honestly? I don't think so.
It's about as weird as your 25% not-straightness, which is, I believe, pretty normal and maybe more commonplace than people think. (But that's a subject for discussion, not for answering your question with.)

We've got gay, straight, bi, pansexual and asexual members in the guild, male and female. (And others that would say I didn't include enough options, but the ones there are for conciseness' sake.)
Just take a look through the gender and sexuality discussion thread, you'll see what I mean.
It's much the same with our sister-guild, the Shoujo-ai/Yuri one.

Like MistressJadeCloud said, I woudn't worry about it too much.
Secretly reading/hiding manga is a pain, though. (I know, believe me.) You can use online manga readers, too.

Depend on how you define the term weird.
If you define it as "off average", then everyone is, in a sense. Which makes you weird if you're perfectly normal!
If you define it as bearing little or no resemblance to the majority, then nobody is, really, since everybody is half-in half-out.
And seriously, why should you care?
You are who you are.
It's much better than being an average.
