Premature Ejaculation is a sexual dysfunction – a term used while describing a person who cannot control their ejaculation no matter how long they last. This is why to one person 10 minutes maybe a long time to have sex, while another views 10 minutes as a poor showing in sex and premature. With seminal leakage, you are so far past premature that you don’t even classify as premature. Seminal leakage is a large volume of pre-come that is usually, under normal circumstances, only a drop because of the tight valve on ejaculation during the build up of sexual energy. While the normal amount is only a drop... saving the semen for the real ejaculation during orgasm, a large amount of pre-come can cause the penis to be too weak to even get to the next level of sexual activity.
