Is it wrong to date your step cousin?

Depends, you don't share blood with them so you can throw out incest; though at the same time that would be frowned upon by many people, my advice is to do it but not let too many people know about it since you will get many raised eyebrows if people do find out.

well i guess it is ok cuz u rn't related by blood but i dont know if ur parents would aprove so..... ask them first
