How Long Do Genital Warts Take To Heal?

I am terrified I will catch genital warts, I spotted a wart in my man s pubic hair. I was giving oral sex and we ve has a lot of sex before & after I noticed it. Since seeing it I have asked him to get a full check up, but didn t mention the wart in case it s not a genital wart. 1) will i catch it on my face or my genitals? 2) how long will it take? 3) Even if its not a genital wart, will I catch it? 4) Am i crazy obsessing over this? Help...
