In MCNR, condoms decrease STD chance from 1 in 3 (33.3% chance) to 1 in 10 (10% chance).1
This is not reflective of real life as when used correctly every time you have sex, male condoms are 98% effective.2 This could be showing a message that condoms are less effective than they actually are.
Mike has acknowledged himself that under-18s play MCNR.3 We should be teaching that condoms help protect you from STDs, rather than falsely being an ineffective method of preventing STDs.
