My boyfriend is interested in joining a fraternity. Do you think this will be the end of our relationship?

We love each other and have been togeher for some time. I have heard these weird stories about fraternites doing things- hazing ( having with the same girl and the last one has to eat her out) I know that hazing isn't suppose to happen but from my undertstanding it still does. I have had friends and know people who relationships have ended because of this. (5+years together) I know this may seem like a stupid question..Mature and honest answers please. Thanks in advance.
