Not normally. It depends on the laws in your state/country.
You can date anyone you want, whether third cousin or first cousin. Going beyond simply dating may raise issues with a first cousin, but not with a third cousin.
it is okay to date anyone who is not a "blood relative". Anyone who is a "Step..." anything is not a blood relative. For instance, it is okay to date your: Step Cousin, Step Second Cousin, Step Third Cousin, etc. it is even okay to date a step Brother or sister, however it is slightly looked down upon by most societies.
no and yes if its okay with your cousin because if it is not okay with your cousin who knows what might happen to your relationship between your cousin and you this actually happened to me but my cousin said no because she still had feelings for him and i said its OKAY there is plenty of hot guys out there why only stay on one :) but then again this is MY answer some people might have different answer and might disagree on what I'm statingand it is okay
Yes. Most people would say that you are supposed to like your cousin.
It is okay to have a crush on your cousin but it is a little awkward to be in love/have a crush on your 1st or 2nd cousin in my opinion
Yes, you could ate your fourth cousin and in some cases people can marry a fourth cousin as they are far removed enough genetically to have children. However, it is the family that may have a problem with fourth cousins dating.
yes, you can. If your dad and your cousins mom are brother and sister then you can date your cousins cousin on your cousins dads side.
Yes, you can date anyone whether fourth cousin, twentieth cousin, or first cousin. Dating is going out and having a good time.
No you shouldn't date your sisters cousin because its wrong and he or she is related by blood.
No! It is called Privacy
No, you are related. There are plenty of people you can "like" that you are not related to.
No
