This is a touchy subject. As many other people have said, its alright. However they are very right when they say its a Social Taboo. You can marry your cousin and have a live, however it will be looked down upon by family and friends, being viewed as an 'odd match'. However i will say this. Sure, try it out. But i assure you that it won't work out. mostly because you are still teenagers. Teenage love never works, not without hardships, and being related only makes it worse. You have so many variables that will get in the way that the relationship to a Teenager will force the attraction to recline, and permanently end the relationship. I think the most awkward thing would be that in the future you get married, your cousin comes up to your wife and sais 'Hes good in the bag, ohhhh ya, i remember.' Thats one variable that is possible in the future. BE CAREFUL YOUNG ONE!
