I'm not sure what to tell you. The situation may or may not explode in your face. But the only way to find out is to be honest. I don't know how you feel about being Chrisitan and having gay sex. I personally believe gay sex to be a sin, but others here believe differently. If you honestly feel gay sex isn't sin, then you have to decide if you want to continue the relationship. If you do, you're going to have to tell your friend. He'll find out sooner or later, and it's best if he hears it from you. I really don't know what his reaction will be, but I see no other choice other than to break off the relationship with his son. I don't think the age difference is much of an issue. You're both old enough to decide for yourselves what you want.
