Protective mum

So I'm 13 almost 14 and my mum always hesitates when letting me hang out with my boyfriend maybe because she think we will have sex but me and him both agree that if we ever did that then we need to be the correct age to give consent because his nate asked if we had done the dirty and obviously we both said no because.....thats stupid (no offense to anyone that had sex at or around 13) so it kind of irritats me that she doesn't trust me
