Speaking as a straight cis male who's on the verge of asexuality, it's been incredibly difficult and oftentimes alienating having discussions of sexuality and sexual insecurities with my other cis male friends because a lot of the discussion tends to veer into vulgarity or jesting. Then there's the conversations you have with your partners and sometimes some of those partners implying that you're not 'man enough', etc.
I understand that a lot of this is due to toxic masculinity but I've gotta say, it's been pretty tough.
