Ejaculating in the anus

A prescription is not needed to purchase Plan B. Three major studies involving thousands of men in the US, Denmark and Finland have shown the same: Low T-lymphocyte ratios in homosexual men. I know the whole STD thing. I have a question, though. I suppose through anal masturbation.

Medical science accepts that it is normal for men over the age of fifty to experience problems with their prostates. These statements are not evaluated by the FDA, as this is a novelty product only to be used as a novelty item. I'm wondering if this is OK to do or if it is harmful to my body because I do enjoy it and would like to continue. I have heard that masturbation affects your brain and memory and might lead to hair loss.
