It seems that you may be having short phrenum. During intercourse due to stretching of phrenum,rupture of phrenum occurs and there is bleeding. You consult dermatologist
or surgeon. After few investigations,he may do minor surgery..like Phrenectomy or circumcision
. Both the surgeries are minor operations and may be done in OPD under local anaesthesia. After surgery, you may be completely normal. I hope you got my answer.
