I have a few that I play regularly,but i'll list them of for you:
Summer in the City you can choose if she can be bi or lesbian early on by FlipDaShit
The better deal & Beauty & The Thug male love intrests are optional both games come with a walkthrough so you can avoid the male sexual encounters,for Beauty & the Thug one scene at the beginning is unavoidable,unfortunately by Zegamez
Casual Desires has a lesbian only option in the options menu & Rebel Duet has the choice to choose between male and female MC & male sexual encounters are optional by ionDivvy
Shelly's Future Past MC Fully Lesbian by SexyShelly
Naughty Lyanna has 2 Seasons Every male sexual interaction is avoidable by DWR Games
Yuri University MC fully Lesbian,one optional encounter with a trans woman by chekkin
Fairwood Retreat MC fully lesbian 87 by Aya Sakura
The Last Embrace has a Vampire MC and has an option for male or female li's,the female shows up first by NoX Productions
How Hard Can It Really Be? the MC is a futanari though,but every li is female & unavoidable, as the story unfolds the harem increases by Waterthose
Actual Roommates 1 & 2 but MC's Fully lesbian by HanakoX
Eruption Imminent but the MC is a futanari and the world in that game is ONLY populated by females normal & futanari by MorriganRae
