I'm just going to say use both the tags. I normally avoid things with gore and usually sexual violence (unless it's a very particular type of story). That could have the effect of turning away someone like me who can in fact enjoy this story. Nonetheless, I think first priority must be having content warnings to aid trauma survivors. Since we've had two rape attempts relatively early on, it's enough to tag the series IMO. A character pinning someone down and making their intentions known while referencing their genitalia is exactly the sort of content that might be upsetting to a trauma survivor.
On a somewhat related topic, I'm not sure this is a true attempt. It may have simply been an attempt to draw the worm out of hiding to get more information.
