Various series I've read or am reading and would recommend to others. 
Bias towards likable well-written main characters, assertive/charismatic male protagonists, harems especially with polygamy.... more>>

Ignore the order, not going to sort them.

Series not on Novel Updates;
- Sasaki to Pii-chan; Fun. A clusterf*ck of cliches and genres (aliens, demons, magical girls, espers, isekai, monsters, secret organizations), similar to 'A Certain Magical Index'. Technically a harem, but sadly unlikely to ever have any romance (Protagonist treats them like daughters).

- Otherside Picnic; It's 'Roadside Picnic'/'STALKER' with a side of yuri. The main characters venture into another world full dangerous supernatural anomalies, searching for a missing person and to make some cash by selling supernatural artifacts. The main characters are well written and there's slow yuri romance. Also has manga adaptation
