Other reason why there is an increase of STI is that individuals are having changes many partners or having many partners and get a STD but don't realise until it’s too late after which time they having sex without using any protection, hence the spread of disease. Another reason that there STI/STD for this rise is because of binge drinking which can also lead to sleeping around with individuals and spreading infections without thought of what happens when they get drunk and looking for some action. An additional explanation being for this increase of STI/STD. Young people like to explore things so when you teach them about thing that interest them, such as chemistry they will go and experiment. The increase is in part because to more testing, and the use of tests, which are more sensitive at picking up signs of an infection unsafe sexual behaviour is also part of the story.
