Novices and newbies discussion

Greetings all. (apologies for my English) Even though I don’t have many posts here, I’ve been following this subject closely for years and currently own an HT V2 standard model that I’ve worn several times now (sometimes just for short sessions, other times for longer stretches). The issue is what happens naturally to me—I believe it’s perfectly normal, but I’d love your honest thoughts—which is that after being locked for at least three or four days, I tend to become overly stimulated. To put it another way, the cage doesn’t completely stop ejaculation (obviously nothing can), and if something catches my attention mentally, I have to calm down quickly or else I’ll cum inside the device. Is this typical? Is it normal to reach an orgasm even a minor one simply because I’m locked up and struggling with self-control? It just happened recently while reading an erotic story; I felt like if I didn’t pause, I would ejaculate right then! How do you handle this situation?
