Besides tired, you are probably suffering from lock jaw and/or a friction burn! Seriously. Your partner’s problem is called ‘retarded ejaculation’ and it can be caused by physical and/or psychological factors.Let’s start with the physical possibilities. Diabetes is associated with retarded ejaculation. And, sedatives or alcohol reduce the sensations needed for orgasm. Orgasm can be blocked if a man has an unconscious fear of hurting his parter, making her pregnant, or if he feels guilty to have sexual pleasure.Sometimes, a combination of physical and psychological factors operate at the same time. Other possibilities include, lack of adequate stimulation which can be due to not receiving enough friction during oral or vaginal sex. Many men learn to ejaculate while they masturbate and they have a hard time (no pun intended) adjusting to the softer touch of the vagina or mouth. If this is the problem, manual stimulation may need to be added to your sexual repertoire. Here’s how this is done: The man is stimulated until he is close to orgasm before beginning intercourse or oral sex. Gradually the time spent touching manually can be reduced as the man trains his body to adapt to the other forms of stimulation.Sometimes inadequate stimulation can be caused by a lack of focus. In other words, if a man pays too much attention to his partner’s reactions, he can lose track of his own sensations, never reaching the high level of arousal required for orgasm. This can occur even though he is aroused enough to obtain and maintain an erection. Sensate focus exercises in which a man is trained to focus on his own bodily sensations can be helpful in such cases.Another successful approach to this type of problem is to do exercises to increase a man’s level of arousal prior to intercourse or oral sex. With this technique, you do not begin intercourse or oral sex until he feels on the verge of orgasm. In this way he learns to enjoy the sensations of nondemanding touching and arousal. Enjoying nondemanding pleasure is especially important to your guy because he is probably feeling pressured to come during intercourse and oral sex. Such pressure is sufficient to prevent orgasm.In fact, many women become bent out over a man’s inability to ejaculate because they read it as a sign that they are unattractive to their mates. When a woman becomes upset, pressure is automatically place on the man, and, as I said above, pressure is the kiss of death to arousal and orgasms.At this point, I think you need to rule out all medical and drug-related causes. Then, if the doctor says he is fine, find a good sex therapist and do some bedroom detective work. Once the source of the problem is found, then exercises will be introduced so that you learn to give him the type of stimulation he requires and he learns to train himself to relax and focus.If psychological factors such as guilt or fear are operating, then you can work these issues through by talking them out.Don’t hesitate to get help because this type of problem rarely improves on its own.
