Remember that all degrees of bisexuality is valid.
You’re bi and you’re hella sexually attracted to one gender, but ‘only’ romantically attracted to another? Super valid.
You’re bi and don’t feel sexually attracted to anyone? So valid.
You have a 50/50 preference? 80/20? That’s valid.
Your preference changes all the time? Still valid.
You choose only to act on your attraction to ‘just’ one gender? That’s perfectly valid.
There’s so many more, but, in conclusion: yes, you’re bi, and yes, you’re wonderful and valid and deserve all the love.
