I need a few ideas for a problem? Cheers?

OK. Hey I'm a 15 year old boy. I'm going to be home alone tomorrow and this week I've been completely hormonal and haven't masturbated at all for 7 days, 8 tomorrow morning. Today my friends were talking about all the different places in their houses that they'd masturbated in, one friend was saying he did it in a field once, but I don't want to do it in public or outside or anything crazy like that. But where are some suggestions for where I can masturbate, some different places and also techniques rather than the conventional classic style. Cheers!
