That's totally cool, obviously whatever you feel is what you feel and that's right, I am not trying to convince you otherwise.
But there is a mountain of difference between "I've never been attracted to penis" and "If you’re prepared to change your sexuality for money then your sexuality was a scam in the first place," which is all my point has ever been.
Don't suck dick because you don't want to suck dick, not because doing so will betray some kind of concept of "straight" upon which you are defining yourself, you know?
I'd argue you are a vegan if you eat chicken for profit though, because again labels aren't religion. There's no score being kept, no penalty applied to you or your veganism because you ate chicken. The moment you stop eating chicken, you're vegan. Life isn't all or nothing, and it's detrimental to think it is.
Again this isn't religion, there is no cosmic scoresheet that is tallying your purity. If you suck a thousand dicks and then decide after #1001 that you're straight, fuck it, you're straight, who the fuck is anyone to say otherwise? There's just no benefit to thinking or living life like there's some outsider tallying your score that you have to appease if you want to identify as a whatever.
