Why over think it? Attend the parade to show support. Go with the bi heart if you want. If someone recognizes you and puts the two together, good for them. No need to make a big deal of it if you don't want to. Being out is all about being able to live your true self freely, not about advertising to the world your sexuality.
I attended my first pride wearing a pink/purple/blue tutu. No one questioned me. No one said anything except that they liked my tutu and shirt (pride in rainbow, both self made because stores didn’t sell “pride merch” at the time :p). Everyone was welcoming, everyone was nice, and it was fun to be “out” outside the house.
You don’t have to be out to everyone to be out at pride, and it’s a good experience to feel that acceptance, especially if you don’t already have it outside your romantic circle. If it still feels strange, be subtle, but be open to saying “I’m bi, this is my husband, unfortunately my gf couldn’t come.” Or whatever version of that feels good to you, but if your pride is anything like my first one, you will leave feeling seen and validated.
The only thing antithetical to pride is whipping yourself over the term upon which you attend it. Just go.
Bisexual
This is a community for bisexuals, their allies, friends, family, anyone curious about us or our community, or just people who want to hang out.
Bisexual means different things to different people, and I'm not going to tell you what it should mean to you. But one thing I will say is that being bisexual does NOT mean being trans-exclusionary. We love no matter what dingles, dongles, or dangles you do or do not have in your pants.
Of course, there are the basic rules. No hate speech, no brigading, no doxing, no homophobia, no transphobia, no sexism, no racism, no illegal material. Rules will be added as needed.
At the moment, we do not have a hard and fast rule over NSFW images or posts, but I will say that this is a community about bisexuality, not for porn. Please don't make me ban NSFW content altogether.
