hi std's do not show in 24 hours your pimple could be just a hair follicle as for the slight pain could be from a small strain the discharge could be just some sperm and the slight pain why urinating may be a burning could be that start of a simple uti. good luck
a pimple on inner side of penis tip after sexual intercourse can it be std? . hi . i am male 21 years old five days ago i woke up with small pimple on tip of my penis on inner side and later that day whitish discharge initially there was slight pain in peeing however now there is only redness in that area and slight pain in left testicle. night before that i was involved in sexual intercourse with a girl and condom was used. i am not sure if this could be any kind of std or just small cut which caused a pimple there and can it lead to urinary track infection.
