If you feel that your cousin would make for a compatible partner…then other peoples’ preferences is not going to (should not) deter you from marrying them. Islam allows it. And if you already ARE married to your cousin…and it’s working…then really…what difference does it make whether someone else finds it acceptable or just plain weird/icky? It’s not going to have a bearing upon your marriage…and if it does (then you have deeper issues to deal with). It CAN make problems with in-laws messy since marriage would make them doubly related…but you can also get some pretty nasty drama in marriages that are not consanguineous.
It’s halal…and then to each his own…whatever suits the individuals involved.
