Would dealing with bottom dysphoria as a transgender fall under other reasons as well? Although I'm not in belt yet but it would serve as a tool to alleviate my dysphoria. Comparing to tucking, chastity belts ensure my genitals are locked in, so "accidents" with tucking won't happen, which would give me sense of security. Also unwanted erections (Which HRT may solve a lot though, as HRT for MTF includes T-blockers) make unwanted bulging, which may also cause tucking to fail. So I feel chastity belt would be more fail-proof way to deal with bottom dysphoria.
