The enemies are avoidable... If you're good.
That said, you can opt out of basically any of the sex scenes by using the very controversial "safeword" button. By using this horrible liberal softboy invention, you too can be not subjected to sex you don't like!
Like I said though, the game is very very small. With a total of like 7 scenes and 3 of them endings, cutting out the lesbians will leave you with maybe 2-3 scenes of content.
