They may not be becoming someone so different, though. Generally speaking, if someone only seems like an asshole when they're drunk they're probably just as much of an asshole when they're sober, just better at masking it.
Breasts aren't like peeing where there's a bladder linked to a single tube that can be forced to let things through backwards. Milk production is anatomically very similar to sweating, where fluid generated in clusters of small glands soaks out through tiny pores in the surface. Imagine a part of your skin that gets sweaty, and pressing it up against your mouth trying to blow air back in through where you sweat. It just would not work out that way.
There are various types of technology in development for needle-free injection of drugs, and they work on principles of generating a lot of force in a tiny area to shove stuff past the outer layers of skin using more direct pressure than you could generate with your mouth and breath.
Putting aside, for the moment, all the very problematic things you declare in this post which are being ably called out by others in these comments already, bisexuality is a thing. It's also a spectrum that can shift around, expand, contract, and otherwise change over time.
Many bisexuals thought they were exclusively heterosexual or homosexual until they found themselves developing sexual interests outside those rigid definitions at some point in their lives, whether early or late in life. It's a thing, it happens to average people regardless of what media they may or may not have been consuming, and it's not all that unusual as these things go.
That being said, you might find it healthier to just take stock of your feelings now rather than trying to blame them on something external as though it were some sort of condition which has been afflicted upon you. Your sexuality just is what it is as you experience it, just like your hair grows in the color it does and your height reaches the number on the ruler it does, and it really doesn't serve you to go down obsessive rabbit holes and develop neuroses about it.
Until you start up a "nice" airline and get the infrastructure going, maybe try to maintain a little of that precious sympathy for those of us with no other fucking choice.
I was once really excited to meet a forum friend on whom I'd been crushing on a little as we were going to attend the same event, and she brought along a forum newbie who lived near her and who I didn't really know all that well.
It turned out my crush and I had just platonically friendly vibes in person, but her friend and I had an immediate major connection and ended up dating seriously for a year.
Barring a very specific set of circumstances or two, "don't interact with any naked men you come across" is probably good advice.
