Can it ever be ok to have sex with your cousin?

It's fine he is just ur cousin it's not like he's u brother it's better to be in a relationship with someone close to ur family and be in love there is no way a guy will break up with his own cousin and trust me it's not disgusting because when a girl is in love with someone not that close like ur brother or nafuo it's ok besides my cousin is attracted to my sister and they don't look disgusting together and were Americans too if u r
