darl,
im gonna be realistic with you aye, some people are gonna be like "yeah, hehehe, in space! hehe"... but yeah umm try
1. the cinema's - the further towards the middle you sit, the harder it gets ;-)
2. in the store room/starewell at work
3. mall toilets
4. random door at the mall, most likely a utility closet
5. clothes shop changeroom - do the old "hey, (to your bf) come in here and tell me if it looks alright......." epic.....
6. at the beach/pool - in the water or out
7. school toilets/changerooms/in class - if you go to school/uni
i mean, if you're crazy you can have sex with someone in the middle of the street... just get creative aye
good luck, and try not to get caught...... unless you're in to that.......
