Boys, when was the first time? Ladies, losing your cherry will do - probably not the best sex (unless you pulled an auld fella).
Personally, early August after doing the Leaving. In Powers Hotel, Kildare St when I was 17. I thought everyone would know it the following day ....... just by looking at me. Remember this was in the old times when leg over among teenagers was not as common as today!
Please, not too graphic as this is a family forum
