Thanks for your question on Chat Doctor. I can understand your concern. You're all symptoms are due to anal Intercourse. Anal Intercourse should not be done because this can actually cause injury to anal mucosa. This kind of injury can cause bleeding from rectum, pain on passing stool. Another possibility is sexually transmitted disease (STD). Anal Intercourse is highly contagious. So chances of STD s are more in anal Intercourse. And this can also cause similar rectal symptoms. So better to consult doctor and get done clinical examination of anus and rectum. Avoid anal Intercourse. Avoid constipation.  Chat Doctor.  You may need antibiotic cream. Hope I have solved your. I will be happy to help you further. Wish you good health. Thanks.
