I and my husband was having sex and his penis mistakenly slip out and enter my anus and i bleed a little and i also have a cut and it also pained me when sitting what should i do?

The blood would be from a fissure in the anal skin created by overstretching. It should self-heal over time if the activity s not repeated. There are over the counter creams like lanolin that may ease the discomfort, but just keeping the area as clean as possible will aid recovery.

Agree with Dr. Ferguson. Avoiding constipation and hard stools will help with healing the "cut". You may take a fiber laxative like Metamucil and drink enough water daily so that your urine is colorless. For the long term you may try to increase your intake of fiber foods.

You may not have any prior anal disease. Sudden penetration can injure anal mucosa causing bleed and pain on sitting. Time is the best healer. Emollients may provide immediate symptoms relief. If you have history of constipation, I agree with previous answers. Next time,use lubricants. Hope it helps.

Use Sitz baths and apply local OTC antibiotic ointment and it should be OK in a few days. If not pl see your doc
