There have been some good posts written in the last few weeks on STDs. Here's my experience.
I've been very bad about using condoms. Every girl I've had sex with I've raw-dogged at some point. Some of them I never used condoms with at all. But I also used to be very scared of STDs. So what that meant was that after each partner I would rush to go get tested. Every doctor I saw would act COMPLETELY UNCONCERNED. Nobody tells you STDs are no big deal, but the behavior of the doctors I saw told me that pretty loud and clear. They would act like I was ridiculous for wanting to get tested. They would test me, and everything would come back negative. Nonetheless, once it burned when I would pee. The test showed nothing, but the pain was real. So I was prescribed some antibiotics and ten days later I was good to go.
Somewhere around two years ago I noticed a little rough bump low on the shaft of my penis. I didn't know what it was exactly. I scraped it off with my fingernails. The little cut healed within a day or two, and you couldn't tell there had every been anything. Around six months later it came back. Once again I just scraped and pulled it off with my fingernails. Once again you couldn't tell there had ever been anything after it healed.
Recently it came back again. Still the same spot. I waited longer this time to see if it would go away on its own but it didn't. It was growing bigger over a period of weeks. Eventually I just scraped it off with my fingernails again. And once again, looking at my dick, you can't tell there had ever been anything there. There's no scar or no mark where the wart grew. The wart could grow back in a couple weeks, a couple months, a couple years, or never. You can't predict it. So far, I've had 3 warts grow in around 2 years. Whenever it does pop up, you can either scrape it off or go to the doctor and pay for them to do it. You could also try this system which is also effective. Having genital warts is less of a nuisance than my bacne.That's right. Once every week or two I'll have one or more big painful zits on my back. This is more annoying than genital warts.
Sex-ed these days is fear-mongering and scare-tactics using worst case scenario photos of stds. If you google photos of genitals warts, you'll find a ton of disgusting nightmarish pictures that are not representative of a normal case. That's not what mine looked like. Mine was tiny and barely noticeable.
You are evolved to fuck, and to survive this fucking and fuck some more. For the most part, any disease transmitted via fucking is going to be mild, because those for whom it was worse than mild, failed to pass on their genes. So, don't worry so much about STDs.
