Hope my post on this topic will be of help to someone.
In my life a little practice of awareness meditation helped me gain better experiences. Applied during sex it is called Tantra Meditation and it helps in both partner reaching orgasm together, or in a longer sex duration of about 20 minutes.
My favourite meditation that I am practicing last 35 years is Awareness/Mindfulness Meditation during brushing my teeth. Earlier it was a robotic act and I used to think about past or future act/activity/instances etc. By being totally aware during brushing feeling it’s abrasion on every tooth, coupled with sensation of paste etc all thoughts slowly got dissolved and only present moment remained. Miraculous it is, as it engrossed all my activities over the period of time.
