Thank you for your message. I have been meddling with the search options and there were some things wrong with it after. I think I’ve fixed that and I also added an other search criteria that allows to search on sexual orientation. I think that will narrow down the searches better. There are some minor issues that I’ll think about how to resolve those.
I’ve changed the module to make it more clear. I hope it works for you (and everyone else). Just let me know if it doesn’t.
