Who bones just once, though? You need a fresh condom for rounds 2&3. You have to assume athletes have the stamina for more than one round. And if they’re going for 2-4 rounds on 30 condoms in 17 days, they’re not boning every day. And all that is assuming that the participants are using all the condoms they’re given, which is unlikely. When have you ever used all the free bullshit you got at some event?
