If you cannot speak up on what you want, you cannot get it considering that your partner is not a mind reader or something of that sort. However, you have to be considerate with your needs and expectations during sex to keep them under pressure which could be detrimental, as discussed later. Be the reason why your partner loves sex by communicating.
The most important part is that it prepares your body for actual sex. The body releases lubricants, especially for the ladies, to have a smooth experience. Also, enough feel-good hormones are released during this session. All this is a stage you should never miss unless you have a quickie.
Let your partner wallow in the thoughts of having you later in the day. It will help not only your sexual life but also your social life. It is so because you will be in a good mood for the better part of the day hence being productive. Thus, to make your sex life better, make your partner look forward to it.
This aspect applies to both foreplay and during the actual love-making session. Please do not rush the experience and enjoy every moment of it. Instead, tease your significant other on what is about to come their way. It creates a craving that makes the actual sex as pleasurable as you will ever experience.
