Me and boyfriend have been together for 3 years. We're both clean no stds nothing. Well we had anal sex last night and I started bleeding and does this mean I have an std
Anus does not have lubrication on its own, while the vagina can lubricate itself. So, partners use lubricants for anal sex. Most probably you have an anal tear, or piles which bled during sex. Consult a healthcareprovider ASAP
