Should I be worried.. or ..?

I’ve been wondering if I should go to the doctors and get checked down there because every time me and my bf do stuff (like fingering) I bleed, but it doesn’t happen if we have sex. And it’s not painful or anything, more like sore ? But it’s also not a lot and it’s more pinkish than red. I think it’s normal, but it’s better to be safe than sorry ¯\_(ツ)_/¯
