Stds and the condom myth

OK so when I was younger I had slept with a few guys, ALWAYS used Condoms, always had regular gyno apts. I was then in a solid relationship and never had any other symptom or wart. Fast forward about 2 yrs. I was at a planned parenthood checkup and my Dr said I have a genital wart. I thought it was a skin tag and have had it for as long as I could remember at that point. She burnt it off and basically told me I was screwed and there was nothing I could do nor get proof I actually had warts. I was obviously upset. Apparently condoms rly do the help prevent stds as much as anyone thinks. If there's any std anywhere else on a person's body u can get it. Hands,feet, thighs,mouths n lips.... so people that sleep around n figure it's all fine because you use a Condom....yeah. it's not fine. I hate that I had to find this out when it's possibly to late.
