Your question is an appreciative one. You must know that when a man and a woman have sex they are totally naked and their body parts touch the surface of the place where they are having sexual intercourse. Therefore it is but natural that if the place where sex is being done is unhealthy then it will affect in some way or the other. One gets different types of infections that might be caused when the penis comes in contact with the surface and specially its front part. The same thing happens in the case of vagina when it comes in contact with bed during sex or vaginal discharge. There may be case that the infections of the bed had caused you to contract the genital warts. You would have seen pictures of herpes and that might suggest a very negative story. But still itis a fact that if one contacts disease of such type then genitals become like that only One has to understand that doing sex in a filthy place is not a viable thing to do as this just not acceptable at all. When you have contracted genital warts then the first thing you should do is to consult a doctor. The doctor’s advice is so necessary when you are in such a dilemma like this. Genital warts are not a thing to be overlooked otherwise the genitals might be affected badly by it. The pictures of herpes show what really can happen. So you should go for a doctor. Good luck for the rest of your life.
