Well, from what I know myself, you'll start to feel a strong urge to masturbate and your body tries to get an erection every time you think about anything hot. Also, leaking and the wet dreams become a lot more frequent. When I was locked for the first time and I was about 5 months without an orgasm or ejaculation, I was having them every week or so.
The testicles (obviously) won't burst π€£, but they get way bigger and sensitive, which you can actually feel quite a lot, especially when you wear tighter underwear.

Well, two months is about the time when you really start feeling it. Since my parents allowed me to relieve myself once a month, it wasn't a problem for me. However, my bf showed me that I can actually use my prostate to ejaculate and he now releases me less frequently.
The prostate milking is a great way to get your sperm out, without actually needing to be unlocked; at least I didn't manage to get an orgasm from it. The procedure itself is quite humiliating, uncomfortable at first and leaves you as horny as before. But at the end of the day, it's worth it.
