I think my husband has genital warts...How do I tak to him about it?

Well, since I was first dating my husband I suspected him of having genital warts... he told me it was pearly penile papules or whatever. So I was okay with it. Now were married I am getting similar looking bumps. Is it warts or...what? I dont have money to see a Dr. and I wanna ask him if he has warts but I dont know how to bring it up with out offending him. Help.
