no sex?

Josephine
my boyfriend and i barely have sex. like we have a very healthy relationship, i love him to bits. it's just sometimes we go like 3 days to a week without sex. it was even worse living at my parents house for the 4 months. i think we had sex like 3 times the whole time we were there.
but is it normal for couples to like rarely have sex? he masturbates a lot, which i dont mind. but... what the heck?
