A lot of people are bisexual and it’s not that uncommon. My daughter is bisexual and she always informs people up front. She is yet to meet a man or a woman who objected to it. Saying that, it’s very personal choice and you might meet people who’d object (I personally wouldn’t date bisexual man so it’s just a choice for me). So you just have to take a risk.

As about not having money because you are in school it’s ok too.

I recommend that in your first message you ask for details on
Something they said and offer your details. If they say they like to read, ask in your message what kind of books they like and mentioned that you like XYZ writer and ask if they’ve read his book etc etc
