Hi Daud and welcome to the forum!
For your rhinitis, you can consult a physician, it is a well-known condition, and you will not have the problem of explaining a rare and unknown condition like POIS. If I were you, I would seek a better treatment than daily Otrivin nasal spray, that is usually not recommended for more than a few days ( ask your pharmacist or doctor about this)
Some members have reported good relief when taking 50 of dyphenidramine ( Benadryl) some time before or just after ejaculation, in addition to taking another antihistamine every day, like cetirizine. See the "antihistamine type" for more details, in my POIS Types Chart at
