For the first time, I gave my new partner oral sex. He is not circumsized and had a lot of foreskin, which I pulled back to do the deed and realized that the foreskin was quite tight around the exposed head. I noticed that his head was redder (than what I am used to seeing) and it looked sensitive ..and there was a slight taste of blood which seemed to be coming from a very tiny tear on the top of the penis under the head. He is 52 years old and has not had sex in quite awhile...we discussed the STD stuff so I do not know what to make of this....we do a lot of phone sex since we live far apart. Any advice out there?
