Me and my boyfriend have been together for awhile and we hangout mostly every weekend, or everyother day, and when we do, we always have sex. When we do have sex, it starts to hurt me and sting. So we stop. We can't last long because I'm always hurting. Is that a bad thing? I don't know what is going on and why? Even when we use a condom or lubricant, it still hurts. If we go anyway, the next day I'll be so sore. Normal? I don't know. But I don't think it is and/or what could possibly be wrong

Never having been a woman I can only make a suggestion to you, apart from the admonishment to stop having sex. Get married and then enjoy yourself.

Sometimes a woman's vaginal area may be slow or fail to lubricate itself. This will cause symptoms as you describe.

If possible, increase the amount of fore-play to give your body a chance to get prepared. Or use a lubricant. KY makes several type of lubricants.

Do you use latex condoms? I found the pain I was experiencing (sounds very similiar) was because I was allergic to latex, at least in that area. They sell latex-free, try that.
