I’ll go first:
I had been curious what it felt like for girls to masturbate so one day I stuck a finger up my butt and tried to imagine it felt as good as jacking off and I thought to my self “I bet that feels great” and that day the seed was planted.
I was very christian when I was in highschool and I decided to try not to masturbate for a month because it was a sin (lol). Well, that idea about how girls masturbated stuck with me, and I was realllly horny by the end of week 2, if I did it in the butt it’s not masturbation right?? so I put a marker up that and I LOST.MY.MIND. I did end up jacking off too so failed on both fronts for the no sinning thing lmao.
After that a few years later once my first g.f. broke up with me I began exploring my more submissive side and I found out I REALLY liked it. I stumbled on to sissy stuff not too long after that, but I didn’t really begin accept and stop being embarrassed about sissy stuff until a few years later when I accepted I was bi and got really turned on by being caged.
This question’s kind of intimidating vs “what were some of the signs”? :P Here’s one of my signs. I was around puberty age (~11-12 yo) and I would anal masturbate with objects I had and saliva (and I would probably jack off afterwards - I don’t remember). Anyway, I played sports, and I had a jockstrap with a hard cup (to protect the genitals from contact in sports play). And I improvised a chastity belt. I cut some slits in the waistband of the jockstrap, I put the jockstrap with cup on, and then I interwove a belt into the slits of the jockstrap to secure it with the belt, and then I fastened the belt and secured it with a padlock 😎
