Pain During Sex?

Josephine
now, it's not a thing that happens all the time or everytime.
my boyfriend and i live together and we're pretty sexually active. and now that we just got back home to our bed after staying with my parents for a few months, we have had sex at least 10 times in a span of 3 days. like more than we have in the longest time.
but when the pain happens it's only like, because he wore my vagina out, like it's sore and i need a break from sex for a few days.
this had happened once with us before when we first started dating and i was less sexually active before. 
but is this normal? like your vagina being worn out and sore from too much sex?
