yeah right there! I agree! There is...ugh...there is a way to show consent in comics and in writing.
Does the man or woman reciprocate kisses from the initiator? Yes.
Does the man or woman moan and whisper things like "This is so hot", "I've been waiting for this", "I adore how you touch me" in response to the initiator? Yes
Does the man or woman move close to their initiator and maybe switch up who is the 'aggressor' or 'take control' of the scene even if they didn't initiate? Yes
THOSE (and many, many more) SHOW CONSENT.
For me, I have to WORK at not showing consent. I have to write things that don't come naturally to me to show a lack of consent. I mean I don't mind, it's fiction, it's my story, but I am just flabbergasted that people think consent is hard to show without it being explicitly said.
It's not.
Just like how people can show a lack of consent without spelling it out ("She moved back away from his hands", "He turned his head away, ashamed of his body", etc), people can show consent similarly.
