Erotica can be wholesome sometimes. I won't vouch for frequency though. All of the Yuri I like that fall into the erotica category I consider wholesome(at least sometimes). Check out my
lists. This is probably only an unpopular opinion with religious types, but I'm a religious type and so are most people I know IRL. Seriously check out the Yuri on my lists, they are guaranteed to be interesting and original works. Yes this is shameless advertising, but I haven't broken the thread's topic, so I only feel mildly embarrassed.
