13 [Similar Anime] Like Hensuki: Are you willing to fall in love with a pervert, as long as she’s a cutie?

"Kawaikereba Hentai" and "Ore wo Suki Nano" are both rom coms based on light novels with similar humor. The main chars are both your average anime protagonist, but in kawaikereba all the girls are weirdos while in Ore wo Suki most girls (except the main love interest) are normies who just like the cool guy. This leads to many misunderstandings and inner monologues in the protagonist's head.

Both have a harem situation with similar sets of characters with random moments of fanservice.

Both are harem animes but hensuki has a twist. The girls all have their own kinks

Harem shows, but with a little added mystery. Our main bro has to uncover the secret one of the girls has. In HenSuki its the person behind the love letter, NakaImo its one of the girls being his sister.

Both of them drift away from the main plot a lot of the time to provide tons of fanservice that loosely relates to the plot.

although both anime has similarity as a harem romance comedy involving sister romance, both anime has a different character set for both the male protagonist and the sister. if oreimo has a tsundere princess pride of a sister with a somewhat servant pride of a brother, hensuki provides the viewer with a sister that shows her loves towards his brother in a blunt way.

both anime is set in a school life background involving club activities and harem with many types of girls. with a small touch of ecchi and not much weight to its story and character development, both anime has a similar taste.

i really like katou megumi of saekano and it will be my main reason for recommending hensuki and saekano where the character of their heroines especially mizuha (the sister of hensuki) and katou megumi (main heroine of saekano) felt the same. both heroine has same way of expressing things with the same flat voice line. although you could feel their love clearly, they express it in a somewhat awkward way.
that being said, both anime also set in a school life background with many similarities in their heroines concept (a big busted senpai, a flat chested kohai, a classmate/someone of the same age, a sibling). all of which resembles different "-dere/fetish".

Both are harem anime that involve really perverted girls. Both harem's include the main character's younger sister. Both shows are basically all about fan service. There is a lot of comedy involved in both as well.
