Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
From what I can appreciate in the picture, it does look like an external hemorrhoids, which probably was triggered by the anal intercourse.
This definitely needs to be physically examined. I will advise you to get it examined by your family physician. For the time being you need to be careful and avoid straining during BM, eat an adequate fiber diet, and also keep applying the Preparation H. The diagnosis can't be confirmed without a physical examination, so kindly get it done at the earliest.
Hope this was helpful,
Regards.
