most of the time when my husband and i have intercourse there's a blood that comes together with his semen.. is it normal?
No, he needs to go and get checked out! there are a whole lot of things that could be going wrong there from mild trauma to the penis to cancer. It's a really common problem with middle aged men, and there could be a really simple explanation, and a really simple treatment to put both your minds at ease, but if you suspect your husband may have an STI, I strongly suggest you visit the GUM clinic too.
