Penis Smell after contact with vagina

Patient: Okay, so, i didn’t really have sex, but i was teasing with a girl. Basically, my the tip penis rub against her vagina and yeah… I also fingered her and later on rub touch penis and yeah. I didn’t shower until about 15 or 16 hours later. And recently, i notice my penis have a different smell to it since that day. I didn’t notice the smell immediately and i thought it would go away but it’s not. i just want to know what’s going on and what i should do. Also, I’m on break, so i also don’t shower that much recently because i dont get out the house… It only smells on the tip of my penis, not the rest of it. I still have my for-skin.
