I am addicted to transwoman and IR porn, I have some questions on rewiring.

So long story short, I have been watching porn for about 9 years now, since I was 12. I am now 21 and I have always been straight, I used to have sex with women, and when I masturbated I used to imagine me fucking them. Recently, ever since I started watching transwoman porn, I cannot get a full on erection, or for the most part it will completely die off if I am not envisioning a passable transwoman penetrating me. So that's the quick run down of it, I am curious if a reboot will fix this? And I know it's not something most people ask, but because of this weird new fetish, do you think that using a FleshLight would help rewiring me to desire a woman's vagina a bit more? Thanks.

Ps: I'd also like to add that I have had irl experiences with transwoman escorts in the recent year, figured that would be useful information on how I can rewire.
