I have never even really thought about it. Being a school team the students are covered by the school's 24/7 rules which covers excessive PDA amongst a host of other things.
The team members are also expected to act in a professional manner. The students at least are of above average intelligence, & they know what this means without signing a contract. Not to say there is not an occasional lapse in memory that is corrected by a gentle reminders.... OK maybe not always a gentle reminder.
