Is there any procedure, on what things to do during foreplay ?

You can start foreplay naked or clothed. It's very pleasant to take a shower together. It seems like the most natural thing in the world to cup a woman's breasts from behind in the shower.

If foreplay gets silly, you can always stop, but it's better than being ponderous and stiff. Talk to your partner. Once, when my partner asked "How much do you love me?": I answered, "As much as Alaska." I love kissing. You can kiss and suck one lip at a time, kiss each eyelid, nibble on the neck, blow softly in the ears, and even nibble the entire back. Respond to your partner's wishes. If she says, "Pull my hair," ask her how hard and then do it. Breasts love to be played with. Most guys like to have their balls cupped and gently fondled, and women like to be licked and sucked in several different ways, but don't plunge right into clitoral stimulation. At any point you can massage buttocks.

In order to really enjoy sex, women have to relax. Maximum pleasure is gained by surrendering. This doesn't mean giving up, it means giving in to lust.

When you r old enough it will come naturally

If you have to ask, you shouldn't be having sex.
