Men can definitely be raped. Personally I'm I guess free use with regards to my partner, unless I object in the moment, she's free to do whatever whenever with me. By virtue of these being AVNs rather than real life, I already go in with the assumption that the women are MC's partners so if they get frisky without explicit permission, it's personally covered already by my own personal foibles.
Irl I'd freak the fuck out though, cause you only get to touch me if I already like you enough to want to touch you back.
One of the most uncomfortable moments in my life was at a strip club when one of the girls came and just plopped herself in my lap to get our table's drink orders. The whole time my brain was like "I DON'T KNOW YOU!!!!"
That's a nice example of why loving and trusting relationships are great, and why people need to feel secure expressing when they're not comfortable.
Taught my kids early on that consent is crucial, in both directions. Told them not to be afraid to say "I haven't given consent" whenever someone does something they are not okay with. Along with, of course, making sure their potential partners are clear before they ever proceed.
Once a relationship has progressed to a point of familiarity, some of the smaller things, and stuff you have done before don't necessarily need explicit confirmation, but you should definitely ask before doing anything new, and stop the moment your partner says to do so.
It's one of the great things with the relationships the MC is building. He always wants to talk with the women in his life and know how they are feeling and what they're thinking before they do anything. He asks for confirmation and consent regularly, and so do the girls. Getting back to the same point they've been before doesn't need the same level of conversation, and they will commonly communicate and tell each other what they want, and/or what they'd like to do. Even when they're joking around or flirting, there is a tone of "would you like to...?" underlying in many of the talks.
Very refreshing, and a testament to Trop's writing skills.
