I was gonna post in his defence, well sort of, earlier. Is there anyone here who did say or do stupid things in the hope of impressing their peers and older people.
No-one here tried to act older/ more mature to ingratiate themselves with people who were just that? And what better way to do so than telling people in a roundabout way 'I am an adult because I am doing that most adult of things - having sex'.
Lee, old chap, think before you leap. My two penneth, for what its worth, is simply that you must consider the following and then decide for yourself what to do:
1. I reckon you are between 15-18. Therefore it is statistically unlikely you will be with the same girl in 10 years time. Thus, it could be foolish to pass up such an opportunity when, in the end, it'll finish anyway. But karma's a right f*cker - if you're gonna knob around finish with your girlfriend first, or it will bite you on the arse eventually.
2. You might be one of the few people that meet someone young and stay with them forever. If you so and you cheat, you might always feel guilty and it could ruin things.
3. Ibiza, and all those wanton hussies who are gonna throw themselves at you (down Holly, down!) will still be there next year. You can go, keep it your pants and if it doesn't work out with your gf, you can fill your boots next summer.
4. If you do cheat, it won't be a one off and its a terrible habit to get into.
5. Wear sunscreen.
