I just saw one if your answers and I found it helpful, but I am having a problem where I get to feel the pre-ejaculation fluid even though I don't have an erection -- no cuddling, no kissing, no hugging, no thinking about sex and no sex -- but by just sitting next to my girlfriend. Please, is there any reason for this?
Even though you are not outright thinking about sex, you find being close to your girlfriend exciting. Your body responds by getting sexually aroused -- not enough to give you a full erection, but enough to trigger the Cowper's glands to start producing pre-ejaculate fluid. Erection and the Cowper's glands actually are independent systems though often similar situations will trigger them.
