Penis tear and swelling after sex. Please help

hello, this is sort of a last resort for me. Ive never had any issues with my penis before but this has been going on for about 3 weeks. My penis foreskin has been getting very dry and after sex it tears and swells up... i like to think it looks like a bamboos arse. I contacted my GP but got told they dont have the capacity to see me. i went to a pharmacist and was provided with some antifungal skin cream. i have only been using it for 2days but i am looking to get some extra advice on what could be causing this. is this balantis? or something worse...
