Secretly having sex?

Jennifer
Okay so I am 16 and my SO is 18 (been together for 1 1/2 years). We haven't had sex in a while and we are desperate to see each other. Both of our parents are super strict so we can't have sex regularly and we can barely see each other about once a week. The only times we've done it was at my house but even then I would be nervous the whole time. Is there any way we can have sex without our parents knowing at somewhere other than our houses? Share your "secret places" please! Thank you!
