As for the menstrual boxers, I've had really embarrassing genital/urinary issues since my endocrinologist raised my testosterone dose a few months ago. That's also why I'll see him this week.
I have to change underwear like 7 times a day, and pads or stuff like that are way too irritating.
Please help a disabled trans guy in distress if you can and want to, thank you for any boost on the main post (I'm embarrassed about this one)
