Allergic reaction or STI

as background, haven't participated in penetrative sex in over a year. no oral in the past 3 weeks. pics attached. does this look like an allergic reaction? i was freaking out and then i remembered that i recently purchased a fleshlight and bottle of water based lube. i have noticed my penis is itchy after use. thoughts? thinking im allergic to one or both. having bloodwork scheduled just in case.

I suggest you rinse it often and apply some oil or natural cream.
Use soap no more that twice a day because if more it will be irritated and dry and itchy.

If the itch persists you might have Balanitis which is easily solved by applying an over the counter antifungal like Lamisil or lotrimin

status update: after a week on antifungal cream, my glans look so much better. i tried taking a shower and just drying off but my glans were super dry and wrinkled. currently using hydrocortisone cream. also, masturbated a few time and now there is some friction irritation to the inside of my foreskin. pics attached. does everylook good except for the irritation at the bottom of my foreskin? also, the white stuff is the hydrocort cream. advice?.imageimageimage
