Seitokai Yakuindomo, Fujimura-kun Mates Recommendations
A lone male Tsukkomi, who once lived a peaceful life, is dragged into a (mostly female) world of boke. Some of the girls have a crush on the lead male, though he is oblivious. Both have sexual jokes, though varying in "maturity level".
-Male lead tsukkomies too much
-Female leads are doing too many sexual jokes
-Both male MCs are acting normal and female MCs are somehow acting abnormal
an ignorant highschool male tsukkomi get dragged to an after school activity by bunch of highschool female boke who will (or is) in love with him and most of the time the jokes are sex jokes.
this could describe both series well.
The mc who just wants to live a normal life is dragged into a lewd world by a group of girls.
