Is that normal?

I lost my virginity in the summer. And ya know, me and my boyfriend since then have sex pretty often when we see each other (basically when I sleep over his house) and when we do it, it still sometimes hurts when he goes in (we’re in November now so it’s been some months for me to get used to having sex) but I honestly don’t think my vagina will be used to it.

I think it’s because it tightens back up after being separated for like a week or two but i don’t know
