Just in case you didnt know, Coming has a sequel called Come Over.
Natsume-san wa Hirakaretai
When I Quit Being a Corporate Slave
Shucchou Host Nyu Boy (this one goes a bit deeper than just looking for sex)
Junjou de Nani ga Warui (pulls a classic yaoi with a really red flag first chapter then gets cute)
I feel like I have more on this list but I can't remember the names if you want to try to sift for more

Looking for recommendations where uke is overall inexperienced but goes out of his way to look for sex. Something like these:
Koi wo Suru Tsumori wa Nakatta
30 Sai Kara no Coming Out
Coming
