Will sex make me fat?

Question: 

Dear Auntie Nangy, I’m too skinny and I want to know if sex will make me fat. I’m a 16-year-old girl.

Answer: 

No, sex will not make you fat but it can make you pregnant or give you Sexually Transmitted Infections (STI’s). If you want to gain weight then start eating more meals, but remember that it must be balanced and healthy and not junk food, and start doing resistance exercises. Resistance exercises are the kind where you use weights and not something like running or cycling. Even if you can’t join a gym you can do weight exercises at home by improvising. For instance, you can use 2l milk bottles filled with water as weights. Auntie cannot tell anybody not to have sex but I can ask everyone to please consider the risks and never have unprotected sex.

Always use a condom.
