Better known as giving head, a blowjob, licking and sucking a male's penis is one of the best liked sexual techniques, which has the great advantage that it cannot cause pregnancy, and also gives the 'giver' an active role to play in love making. Just as with ordinary kissing and with cunnilingus, it is handy to know some basics.

• It is very important to be very careful and gentle doing fellatio, and use plenty of saliva.

• The first time you perform fellatio is probably a bit scary, so prepare for that by familiarizing yourself with his body beforehand. During 'ordinary' sessions you must first feel the penis against your leg or other body part, and then learn to touch the penis with your hand. You must be able to look at it, both when it is small and when it is erected.

• Also you have some practical experience with manual stroking (masturbation) leading to orgasm and ejaculation

• Before fellatio you decide how far you will go. You must be on top. The first few times you practice fellatio it is probably wise to hold the penis, kiss it lightly, watch it grow, and play with your tongue, put your lips over the head of the penis, enclose it in your mouth for just brief moments and hold it away from your mouth when he climaxes, which is just before he ejaculates.

• In fellatio it is a good thing to keep communication going, touch and caress him, exchange signals of pleasure, ask him if you're doing it right. The most sensitive area is under the glans (head), where it is attached to the shaft of the penis with a little muscle called frenulum. Remember to keep plenty of saliva round your tongue and lips, and lick that spot for maximum effect

• Hold the penis by fellatio with your full hand, or with just your thumb and index finger encircling the base, squeezing lightly from time to time to make the penis stand up even harder and grow to maximum size.

• You can observe the excitement in him mounting by the fellatio, since his breathing goes faster, his muscles tense, he may sigh or moan, his testicles rise and the scrotum contracts against the base of the penis.

• If you put your mouth around the glans of the penis, keep your teeth away from the sensitive skin. In fellatio there should be no violent or monotonous blind movement on your part, but conscious, pleasure-giving motion with some variety, just covering the glans and coming up and then coming down all the way as far as you feel comfortable.

• Only by the time he is sufficiently aroused by the fellatio to be on the way to a climax do you continue the movement you are making, stimulating the same area persistently, but of course without causing any pain or discomfort until he reaches the climax and a second later ejaculates, so you have time to move your head aside.

• After sufficient experience with fellatio, under safe conditions, and if you like to try it, you can let him come inside your mouth. You can decide to swallow the semen or hold it in your mouth and then let it flow from your mouth onto his belly or leg. Have a tissue or handkerchief at hand to wipe it away, but it can also be rubbed over his body as part of the love session

• The taste of semen is like oyster without salt, and it's a little sticky, so keep a glass of water at hand if you want to rinse your mouth.
