We have a limited amount of blood available for non-essential functions such as solving sudoku puzzles and sex. So try to clear your mind before having sex or measuring your penis size. Meditation might make your sex better purely from more efficient use of spare blood around your body.
Poor blood circulation
Poor blood circulation often from stress, excess weight, sedentary lifestyle, lack of exercise, depression, and other reasons will definitely interfere with the strength of the erection.

Time of the day
Time of the day matters for the strength of the erection and the corresponding penis size measurements.

The more blood you have available the stronger your erection is.
Method of achieving erection
Ways of achieving an erection matters. One study found that men who gained an erection via oral sex, had the hardest erection. This may be due to oral sex being more fun or more arousing. The mechanics of oral sex may also contribute to the strength of erection, similar to that of penis pumps which are used to treat erectile dysfunction.
Dehydration or not having enough water in your system will have an impact on the size of your boner. You need water for plasma, for the blood to circulate around your body. Alcohol dehydrated you and you may find that the effect is similar to that of being exhausted after losing a lot of water through exercise. So keep in mind that you need to drink water in order to get maximum erection strength.
