Ahem, not just that. Sexism is demeaning women also.
I’d say this would make sense IC, but would work much better as an “increased attractiveness” bionic rather then the rather… controversal state it is now. Besides, wouldn’t the penis size modifier CBM be completely useless since people don’t exactly look at your dick (which would need to be exposed for this to make sense or large enough to make a bump) and go “Yep… this guy’s trustworthy”?
