they're all anime in the ecchi & harem series genre and what else and i have already watched them. it's all in the adult (18+) area bc there is a lot of nudity shown by the female characters, sex scenes are included in some anime that make it look like hentai, and mostly they are series like where the main male character builds a harem with female characters... (i warn you in advance, some of those on the list are abt violence, rape and also incest, and other dirty uncomfortable things. just a warning of what you're about to see.)
here are harmless things here too ...like romance but sexy scenes are shown.
so i will update more series when i have watched something like that.

Reito Mizuhara is a medical student at the National Advanced Medical School in Tokyo who contracts a rare, lethal disease called cellular sclerosis. In order to be treated, he is put into cryogenic sleep for five years. Upon awakening, he learns that a year into his slumber, a worldwide pandemic broke out, caused by the novel Male Killer (MK) virus which exclusively afflicts males and has killed all other men on Earth. Fortunately, Reito and four other men were spared during their cryosleep and are now immune to the virus. As the only men left in the world, they are thus tasked with mating with as many women as possible to repopulate the planet. However, Reito is committed to his childhood friend and sole love interest, Elisa Tachibana—only to learn that she went missing three years ago. While the other male survivors adapt accordingly to this new world, Reito instead chooses to pursue Elisa, fight never-ending temptation, and investigate this mysterious virus.

In their teenage years, few things can hurt people more than the heartaches that come with unrequited love. Such is the case for Natsuo Fujii, who has found himself entranced by his school's ever-cheerful teacher Hina. Deflated by this unreachable desire, Natsuo humors his friends and attends a mixer. There he meets Rui, a girl whose lack of excitement rivals that of himself. After bonding over their mutual awkwardness, Rui takes Natsuo to her house and asks him to have sex with her, hoping that the experience will stop her friends from treating her like a clueless child. With his hopeless feelings towards Hina still on his mind, Natsuo hesitantly agrees. Equally unfulfilled by their "first times," the two decide to part ways as strangers. However, before he even has a chance to process this experience, Natsuo's father drops a major bombshell: he is getting remarried, and his new wife Tsukiko Tachibana is coming over now to meet Natsuo. As if that was not enough of a shock, her daughters—and, in turn, Natsuo's new sisters—are Hina and Rui Tachibana, the woman he's in love with and the girl with whom he shared his first night. Now, Natsuo must come to terms with the feelings he has for his step-siblings as his eyes open to a darker side of love. [Written by MAL Rewrite]

As his school days draw to an end, Yuuki Wakura worries about his future. While lamenting the prospect of living an ordinary life, he is suddenly drawn into the world of Mato: an alternate dimension filled with dangerous monsters called Shuuki. Over the years since the existence of Mato was first confirmed, incidents of people accidentally wandering into the other world have become commonplace. To combat the threat of the Shuuki and rescue victims like Yuuki, the all-female Demon Defense Force was established. Its members have been blessed with the power of "Peaches"—Mato fruits that grant supernatural abilities only to women. Though Yuuki's situation is dire, he is saved in the nick of time by Kyouka Uzen, the chief of the Demon Defense Force's seventh unit. Despite Kyouka's impeccable skills in battle, she has long been held back by her Peach-granted ability, Slave. Slave allows Kyouka to put a living being under her control and draw out its strength, but the Shuuki that she had enslaved until now had all proven to be exceedingly weak. When Yuuki and Kyouka become surrounded by a horde of Shuuki, Kyouka resorts to something she has never tried before: using her ability on a man. To her surprise, Yuuki's slave form is much more powerful than she could have imagined. Believing the young man to be the key to unlocking her true potential, Kyouka invites Yuuki to join the Demon Defense Force—but not as a regular member. [Written by MAL Rewrite]
