What happens when you come?

When you come or ejaculate, white semen containing sperm comes out of the end of your penis. It can happen during sex, during masturbation or even during the night in a dream. It's perfectly normal.

I've got blood in my semen. Is it serious?

This is can be very scary but is usually harmless. A bit of rough sex or masturbation can cause it so you only need to seek help if it keeps on happening. In fact, only one in five cases have an obvious cause but very, very rarely it can be a sign of something more serious so see a doctor if it lasts a month or more.

One less serious cause is Orchitis: the inflammation of one or, more rarely, two testicles, usually as a result of a bacterial or viral infection. Common causes include mumps - approximately one in four men who catch mumps will develop orchitis - and sexually transmitted infections such as chlamydia and gonorrhea. In epididymo-orchitis, the epididymis - the sperm-carrying tube attached to the testicle - is also affected.

I come too soon/not soon enough.

The main problems with ejaculation are coming too soon or not coming at all. If you come too quickly, remember this: every young man on the planet has come too soon at some time. It can be very embarrassing but, like death and taxes, it's a fact of life. In twenty years time you'll be wishing you still had the problem.

Coming too quickly is often called premature ejaculation. Taking too long to come or not coming at all is called retarded ejaculation.
