Can i get a discharge from my penis after masterbating with lotion

Could be the lotion: You could be getting some of the lotion coming out of the urethra and it looks like discharge. After regular ejaculation it's also common to have some normal discharge. If you're having unprotected intercourse, concerned about a sexually transmitted disease or this is something that's happening regularly, there's no harm to getting checked by your doc and having an std test.
