Yeast infection? Please help me

Patient: Hi, I’m 18 years old (female) and sexually active with my boyfriend. We are both completely clean. Lately though sex has started hurting a lot, I find that if I leave having sex for a week or two then it hurts with entry, my vagina seems to tighten up to the point of the pain of losing my virginity again.. We use lots of lube because of my pain, sometimes I bleed so My sex drive as dropped dramatically. What should I do about this? Also on another note… I’ve noticed a red little spot on my inner lip of my vagina and it hurts to touch it and it hurts to go to the toilet. I don’t know what to do about this or even what it is? Please help me. Could it be a yeast infection?
