need advice regarding celibacy and masturbation (nsfw)

i’m specifically interested in catholicism and orthodoxy, but i’d love advice from anybody. (i am a teenage girl who converted last year if this matters)

i am celibate now, and haven’t had any sexual relations in real life. i have little to no interest in sex or relationships after having some bad experiences with LDR , and i am completely avoidant of them.

i have always struggled with frequent masturbation, but i have no lustful thoughts towards people nor want to act on anything sexual. is it immoral for me to indulge in masturbation as someone who will not act on lust? or is masturbation lust itself?

(i am giving up things for lent, and i’m wondering if this is of high concern due to the excessiveness of it)
