hi as you had just washed it and it was no doubt still wet then no your ok if you stress over this it will make you very ill. just be the man and tell yourself your ok man it out. good luck
after ejaculating. i washed my penis with warm and cold water. my penis tuchd outside of sink the bathroom is shared. in a dormetry/ hostel style environment. can i catch anything? would i have to wait for any signs to show physically whether i have caught anything?
