I think I know what the problem is. The sex scenes look like pornography, they do not look like people making love. For example, the picture of the two women almost kissing, tongues dangling like Gene Simmons. Who does that? Actors in porn movies.
Were you, by any chance, involved with a game called "Regency Love?" This isn't the same as that game, but there seems to be a similarity of characters and the writing style seems familiar somehow.
