What is the most intimate romantic/sexual thing
could i find a girl that would care for me like this on bumble?
In concept, sure, but likelihood is low. I work with a lot of men who have had some serious challenges with Bumble. Bumble was successful in it's marketing but mechanically it's functionally identical to Tinder. The whole "women message first thing" is true on a technicality, but it doesn't change how Tinder works. Both parties have to swipe, both have to swipe positively on each other, but then guys get put in a limbo of being unable to send anything. In concept, it was designed to empower women and minimize harassment, but in execution it just adds an extra step. Additionally. most heterosexual courting rituals in the western world usually put a pressure on men initiating/pursuing way more than women.
Tldr Bumble often makes men feel even more powerless seeing that a girl matched with them and then just having to sit there and do nothing looking at a screen saying "____ matched with you. Wait for her to make the first move!". Then never getting a response at all, or if you do, statistically it's more of just "hey" and then the burden put back on you to lead the conversation.
If you're looking for an actual partner, personally and professionally I ALWAYS recommend OkCupid. It's free, very autism friendly, and immediately allows for both weeding out hard no related topics, and for having women take waaaaaay more time exploring your profile before swiping instead of just zooming past your first picture. Match frequency and quality is much more likely there.
