I feel like Quinn was supposed to come off as a horny dude in his talks, and I think that is a constant throughout his content. His conversation when meeting Whisper, his training with Tugs and whatever small interactions he gets do paint him as a man that readily follows what his dick tells him to do. He jokingly says (up to the reader if they find it humorous) that one of the reason he wants to help Cait is so they can have a make out sex afterwards.
I do have to admit that his Brienne and Ryn talks do straddle the line in terms of how uncomfortable they can be, and little misogynistic I can't lie, but those always read to me as his initial, shallow impressions.
I do know that some companions recieve updated talks after some time passes in game, so maybe that was supposed to be case with him. After we get to know him better, maybe he starts appreciating the woman of our group beyond surface level appeal aka: do they get him hard or not.
