* Nightwing (DC) On two occasions, once when Mirage his teammate used her powers to look and act like his then girlfriend Star fire to have a sexual hookup without his knowledge, and a second when after a traumatizing battle he is taken sexual advantage of by Tarantula when he is disassociating. Both events are treated as jokes by the in-universe superhero community.
* Hughie (The Boys) When acting undercover he is cornered into a bdsm scene without his consent and is raped. The Director of the episode referred to the incident as hilarious.
* Batman (The Son of the Bat Storyline) Is on the border of this trope as the initial rondevue between Batman and Talia Al Ghoul was consensual but then was ret conned into her drugging him and the ret coned again to be consensual again? But in the Movie a quip from Batman reveal that they went with the drugging for that continuity. 
* Izuku Midoryia (My Hero Academia) Had the naked super villain Toga press her breasts against him, against his will while she is in disguise and is treated like a joke by the two resident pervs in his class. 
* Green Arrow (DC) While injured and hoped up on painkillers he is taken advantage of by the Russian assassin Shado and was given a playboy reputation for years for it. His wife Black Canary is a refreshing breath of fresh air as she doesn't hold him being assaulted against him and tears people a new one when they joke about his rape.
* Cyclops (Marvel) After his Wife's Death Cyclops sought Emma Frost for therapy where she then used her position as his therapist to coerce him into a psychic sexual relationship. He is then given shit for it for years over his "cheating" even though Emma was the one who initiated the relationship when she had him in a vulnerable position and used her psychic power to know everything about him.

(Weirdly Common Trope) Male Heroes who have been sexually assaulted by women and have had the event treated like a joke.
