The criteria is whether or not you can control the impulses. If you think sharing living quarters with a bunch of other guys is going to knock you off the wagon, so to say, then probably not.
I have worked with vocations who have SSA. Women usually have a worse time around the ovulation part of their cycle. This is because their hormones are driving them crazy, but during other parts of the cycle, they are ok. Once they recognize that, it’s a mind-over-matter deal: if you don’t mind, it doesn’t matter. The temptations are no more than wind passing your face when going at high speed.
Can you look at Our Lord or a male saint without lusting? Try to develop a greater respect for others. If you don’t like being lusted after, then imagine what a righteous person would feel if you lusted after them. If one gives in to temptation, imagine the outcry. Then you’re out of a job.
Keep in mind that pagans lust after the same sex as worship of their foreign gods. This should lend some perspective.
