Tips for a big penis 🙈🙈🙈

The guy I’ve been having sex with lately has a pretty big penis. To the point where it hurts most of the time we are having sex. Mostly in the beginning when he first puts it in, but sometimes it’ll hurt throughout the rougher he gets. Does anyone have any tips on what I can do to get used to taking it? I don’t want to stop having sex with him but I also want to enjoy it the whole time instead of half.
