reduce pain during intercourse

Normally, penetrative sex involves the thrusting of the penis inside the vagina. If the vagina is tight, the penis, when inserted inside the vagina, exerts immense pressure, making it painful for the woman. If the length and the girth of the penis are big, it creates more friction within the walls of the vagina, which makes it pleasurable yet painful. Some women can bear the pain but for some, it is so much that they even lose interest in sex. . Using a lube can make the penis and the vagina slippery and greasy which allows the penis to penetrate with ease, not exerting much pressure and not causing much pain to the woman. Also, sometimes, the pressure can also give pain to the man's penis and so, using a lube makes it easy.
