It is my strong halachic opinion (I am not a posek, and my comments are not LeHalacha and not L’Maaseh) that any male who is (also) attracted to the same gender, should be absolutely forbidden to go to the Mikvah, other than in exceptional circumstances where it is necessary and only then, when they are the only person in the Mikvah, and supervised from outside, to be so (in a quiet tzniusdik way so as not to embarrass)
Ask your Rav for his Psak on such a matter. Point out that Shulchan Aruch already wrote that it is forbidden to stay alone (Yichud) with a male, if there is a concern that they have proclivity towards same gender attraction. Your Rav may not want to reveal his name (everyone seems to want to go under the radar today) but I’d be interested to know what your Posek, anywhere in the world, feels is the Halacha for someone in the class above.
(If Mikvaos are re-architectured, things may change. I’ve argued they should be)
