Sex Techniques: Unfortunately or fortunately, depending on your perspective one does not go to the doctor to learn how to have sex, when to have sex or with whom to have sex. There are some very strict ethical boundaries when it comes to questions such as yours. I often recommend to patients that they get at least one good guidebook to sexual technique so that one can read of ways to improve sex pleasure.

Some possibilities: For difficulty reaching orgasm, his primary care doctor can check things out. Some reasons for such symptoms include: being tired, having other things on his mind, psychological stress, having had an orgasm recently, taking certain medications (some common prescription medications can have such a side effect), older age, nerve problems, circulations problems, etc...
