Can you have a "normal" sex, if you have this fetish ?

[asasasasasa]

First of all, i've been into fat fetish since i was 15, in my puberty i always turn on by feederism, fat bellies, stuffing, etc. Even i masturbate with this kind of fetish

And now i'am around 18, and i wonder if i go into relationships with girl i like, can i "turn on" and having a normal sex with her? because i've been masturbate to those fat fetish porn category

of course i like this girl physically, she's beautiful, have a "normal" body. i'm worried that i can't have a normal sex with her

this is so depressing to me
