Reacting first to the title of your question, before reading anything else: No STD can start to cause symptoms in under 24 hours. 2-3 days is the minimum, and for most STDs it's a week or more. Now I have read the rest, and also glanced at your discussions on the STD community forum.

The incubation period of STDs depends on which STD you were exposed to. The time from exposure to when symptoms appear can range from a few days to as long as six months. In addition, some STDs don't always present with symptoms. That means you may be infected but be unaware.

The minimum interval for symptoms of STD is probably 24-36 hours, and even that would be rare and applies only to a few infections, such as gonorrhea -- and even that usually has a 2-5 days incubation period.
