Vaginal sex is not always the most effective way to achieve the coveted orgasm. First, the partner may have weak vaginal muscles that do not provide the necessary "girth" of the penis and its intense stimulation (although, in truth, changing positions can sometimes be an option). Secondly, not in all situations a man can be helped by standard frictions, and the possibilities of the vagina in terms of various stimulation are limited. In such cases, oral and manual techniques can really help out. There is a huge variety of them, but if you want to speed up your orgasm with the help of them, the main thing is to follow two simple principles: make movements with emphasis down (the so-called "entry principle"), and keep a monotonous rhythm.
Depends on the guy. You can try different options from spontaneous in different parts of the house (and not only), to vanilla tenderness under the covers. Contrary to common stereotypes about primitive male sexuality (compared to incredibly complex female sexuality), orgasm is not "twisted and fused" at all. The brightest orgasm in a man occurs after prolonged various stimulation, including not only erogenous zones (and these may not be the most obvious, for example, ears, belly), but also the brain! The guy should be in the process of thinking and part of the impact can be a prelude in the form of even an ordinary conversation, furnished in a special way. However, spontaneity can also give a vivid effect, but then the process itself should be longer.
To summarize, if we leave out the details, then there are two key conditions: not too short duration of the entire process (from foreplay, if any, to orgasm ), and the second is the involvement of consciousness.
