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 3-5 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 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!
