All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
The scholars differed in opinion in regard to the possibility of a human having sexual intercourse with a Jinni. Some of them denied it, and some of them confirmed it. Anyway, you should turn to Allaah and supplicate Him as much as possible, especially with the following Prophetic supplication: "Allaahumma rahmataka arjoo falaa takilnee ila nafsee tarfata 'ayyn, wa aslih lee sha'nee kullahu, laa ilaaha illaa ant."
‘O Allaah, it is Your mercy that I hope for, so do not leave me in charge of my affairs even for a blink of an eye and rectify for me all of my affairs. None has the right to be worshipped except You." We also advise you to continue performing Ruqyah, and be steadfast in performing your religious obligations and other acts of obedience, as this is beneficial in all cases; may Allaah cure you from what you experience. Nonetheless, you should avoid magicians and fortune-tellers as they will not benefit you in anything, rather, they will harm you.
Finally, it should be noted that what you experience could also be a physical problem, so you should consult trustworthy doctors.
Allaah Knows best.
