Worried about boat party/booze cruise in Magaluf

Hello, I am going to Magaluf this summer and I have got into going out clubbing etc within the last year. However, my friends are really keen on the boat parties and after seeing the programmes I am worried that it will be too much for me. The sex games (I'm not that experienced etc) and I am very conscious in a bikini etc (short size 12). Has anyone been on them? What are they like? Any advice welcome!
