Slight ripping and pain dying intercourse

So I've had this issue for a while, few years I think. I don't have any pain during actual intercourse, unless I start drying up (and that's annoying and don't know why that happens). But when I first start with my partner it hurts to get him in and when we finish and I go pee I always find a tiny bit of blood, just a little bit. I don't like how it feels cause it hurts. I tried talking to a doctor about it but he was no help :/ any ideas?
