Truth be told, I'm fairly strongly convinced that the majority of the 'romance' writing that is tied to the intimate sequences specifically is all written entirely by-males-for-males, and it shows.

I made a thread about Minthara's romance, if you're interested: https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=750763

It discusses the many problems with the writing to either side of the scene, but it does delve heavily into the 'naughty bits' as well, and how the design and choreography there does even more damage to the characterisation and and coherency of the sequence.
