I think you are suffering from premature ejaculation
. This can be due to several reasons and the following things can help with that
a. You can consider using a local anesthetic
gel. The gel will contain either lidocaine
and is available at the pharmacy
b. The Masters Johnson method is also useful. This would comprise of the following steps
Your partner places her hand so that her thumb is on one side of the man's erect penis (the nearer side to her when she is facing him).
Her index and middle fingers are on the other side.
The index finger is just above the ridge of the glans
(the 'head'), while the middle finger is just below the ridge.
When the man feels that he's near to a climax, he tells his partner.
She then squeezes his shaft firmly between her thumb and the other two fingers.
c. The stop start technique is also useful. For this, the man is encouraged to masturbate alone. You would need to set time aside to be private and to masturbate with dry hands. Then you need to masturbate almost to the point of ejaculation and then stop. Repeat this three times. On the fourth time, you are permitted to ejaculate.
Also, about the chest hair. There is nothing that can be done about it, I am afraid. Its something which occurs with an increase in the age and some people may not have any chest hair at all.
Hope this helps
