This blog entry is addressed to both sexes, but especially to women who may read my blog.
As regards oral sex, fellatio (cocksucking) is performed upon men and cunnilingus (eating out) performed upon women, may be risky for sexually transmitted diseases (STD's). We live in an age when sex partners must take precautions. In taking such precautions, you are showing concern and regard for the safety and wellbeing of your partner in sexual congress.
I post this entry as a gay man. I've never had sexual intercourse with a woman, let alone had serious intimacy with the fair sex. I have only had a few sexual encounters with other men, most of them very pleasurable. So my tips for fellatio, cocksucking come my sexual experience with other men.
I truly believe that most males are not only hardwired for masturbation, but also giving and receiving fellatio, head. I believe that even straight, heterosexual guys are a natural when going down on other guys, if given the chance, even though most straights look upon cocksucking as perverted, queer. But hey, most guys love to masturbate if they are truly into their cocks. So many guys carry over their self-pleasuring that is the essence of masturbation to giving oral pleasure to another male. Admittedly, most guys, even straight guys, love to be sucked off. There is nothing more pleasurable than a warm, moist mouth making love to your penis. It ranks up there to fucking cunt (even ass). And what great pleasure for a guy to experience an ecstatic orgasm, with a copious ejaculation of his semen into an eager mouth!
It goes further than this. Sucking is a basic bodily function of infants. An infant instinctively sucks the teats of the mother in its pursuit of mother's milk. I believe that cocksucking among males is a carry over of this impulse. The male cocksucker uses his masturbatory experiences (what gives him pleasure) in giving oral pleasure to the penis of the other guy. Hence the cocksucking binds the cocksucker and cocksuckee together in intimate sexual pleasure. Many such guys form relationships during which they service the penis of the other guy time and time again. In my many chats on mIRC #jack-off-str8 over the years, there are many guys out there (here in the USA) that form these special friendships. They will suck off their buddies once or several times a week. I find it thrilling that a committed, experienced cocksucker will service one or several men even weekly.
Now circumcision enhances not only the appearance of a guy's penis, but also his suckability. Circumcised guys don't have the problem of smegma, "head cheese" accumulating on their glans as uncircumcised guys who don't retract their foreskins and bathe on a daily basis.
So this leads to the tips section of this blog entry for adult female readers. It's a known fact that many women prefer circumcised guys for sex, especially oral sex. The cardinal rule about fellatio is be careful not to use your teeth upon a guy's penis. Not only is it downright painful, but teeth on penis can lessen greatly the ardor of sex period. Next, take your time exploring a guy's penis with your lips and tongue. Most guys will become delirious with pleasure when you focus (at least) this oral exploration upon their glans. Use your lips and tongue lathering a guy's meatus (piss/cumslit) of his glans penis. Many guys have a large meatus, so tongue fuck his piss/cumslit repeatly. Many guys will quickly become so sexually aroused that they will ooze or leak a steady stream of clear, viscous pre-seminal fluid, precum, from their glans meatus. Also explore with your lips and tongue the rim or flange of his cockhead. Many guys find that both quite sensitive and pleasurable. Finally lathe the groove from the meatus to the frenulum (if he has one) or frenulear area on the underside of his penis. Do all these things over and over again. He'll love you for all this.
What I described above is an essential activity in foreplay. But as we know, foreplay in sexual relations can begin a good while before fellatio, cocksucking. Subtle visual, olfactory, and tactile impressions and signals start the process towards sex. Also since I am a gay guy and haven't had any sexual relationships with women, I can't give clear guidance on cunnilingus, eating out a woman's cunt, but cunnilingus is also a vital oral activity in the sexual repertory of heterosexual partners.
Getting back to what I described about cocksucking above, which is the an part of foreplay, several things can happen. First, it can lead to serious fellatio during the cocksucker in his bobbing motions can deep throat his partner, suck his penis to the pubic hair, or let his partner fuck his face. Often serious cocksucking results in a delicious sexual climax. Swallowing a guy's load of semen is gratifying both the guy swallowing and the guy ejaculating. Second, it can lead to the main course of sexual intercourse, fucking.
Now there is a form of fellatio called 69, in which both partners suck each other's penis, often to climax. Somehow cock to mouth fashions a live (even an electric) sexual energy in a circuit that is irresistible to guys into 69.
Long live fellatio, cocksucking!
