Yes definitely, a big focus for me was to keep things mostly believable/somewhat grounded while of course still getting Sam into a lot of situations that involve sex.
Single playthrough of the game is roughly 4-8+ hours depending on how much of the optional content you engage with (finding and reading the hidden stories. Chatting with guys on Findr, watching full vids, replaying for different routes etc.)
I wouldn't class it as highly replayable as it's mostly a linear story with off-shoots and slight differences based on choices, things like if you're the top or bottom etc, so could play it twice/maybe 3 times to cover all the options but yeah not super replayable in the sense you'll see completely new things on each playthrough.
Hopefully that answered your questions!
