It's the ultimate communication of love, and to be deprived of that can be frustrating in the least. The solution then, is not to "keep your clothes on," but to find a way around it so that you can express yourself.
EDIT: She state that they're living with they're parents, but that they're in college- don't assume they're "leeching off their parents." Why are you assuming that she's going to get pregnant? For all you know, she could be packed full of contraceptives. They're healthy young 20 year olds who have been together for four years. Telling them to keep it in their pants until they're done with college, have a job and are moved out is really kind of absurd.
