The exercises to strengthen your PC muscle are very good for making you last longer. You can also do this while you pee...when you get going stop the stream by flexing the PC muscle, see how many times you can stop and start and try to build on that over a month...you will notice the difference in bed.
As for being a better lover, there is no cookie cutter formula. Each girl is different and each girl has her own erogenous zones. Clearly we all know about the neck, ears, small of back, inner thighs, nipples, and pussy, but I've had girls get off on the most simple things. One girl absolutely loved it when I nibbled on her wrists...I took the hint and while having sex pulled her hand up and made light contact with her wrist resulting in a wall-crumbling orgasm. Another girl really got turned on when I sucked on her earlobe, for some reason it was only the right one, the left barley gave her any sensation. A few girls I've been with liked to be choked as they orgasmed, one even begged me to slap her. I felt apprehensive doing it, but her satisfaction afterwards left no doubt in my mind that it was what she wanted. Another girl really liked me to clench her ass right before she would come...Lol this chick was a real screamer. The list goes on and on, each experience teaches you something slightly new and thats the beauty about women as no two are exactly the same.
A surefire way to pleasure a woman is to ask her what turns her on. Do this while making out, make it a playful/flirting thing. Go for the sure bets first (i.e. neck, jawline, ears, etc.), listen to her responses if she starts breathing heavier than she likes it. Don't be shy, be cocky as you are now in control. Ask her, or better yet, tell her "you like that", she will undoubtedly say yes or moan mmmmm. This is the perfect time to ask "what else do you like", even better, use the word "erogenous"...for some reason girls like this word, perhaps it makes them feel more sensual than robotic. As she tells you what she like move to those areas, ask her "like this" as you caress and kiss those spots. As you make your circuit around her more publicly accessible spots you'll be surprised how soon she will ask you to grab her breasts and on occasions will shyly beg "touch me"(indicating they want you to go downstairs). Experimentation is key! A combination of forceful grabbing and light touching is the push-pull type of stimulation that really drives girls wild. But you must remember that it is all about confidence, you have to project sexuality and complete competence in what you are doing...if you feel shy or weird doing something, she will sense it and begin to feel insecure. Women like nothing more than a man who KNOWS what he is doing....it is a subtle form of dominance that triggers that primordial desire to be at the animalistic mercy of a real man!
As for making her come, clit stimulation is by far the easiest way to push her over the edge, but combining clit stimulation with G-Spot contact will plaster that doe-eyed I love you look on her face afterwards. Try different positions: the higher her legs, the more G-spot stimulation but the less clitoral stimulus. If you enter her from behind, put your hands to use, grab her ass cheeks, rub her clit, tease her breasts. The secret is try everything and adjust according to her reactions. You don't want to come off like a pornstar changing positions rapidly and pounding away like a jackhammer...give everything a chance to develop. Tease her with several short rapid thrusts and throw in a deep slow thrust every now and then and watch her body beg for more (plus switching the depth of penetration will make you last much longer
). Some swear by an 8 to 1 formula (8 short thrusts for every 1 deep thrust), I don't really like to keep count. Oh and one more thing, TALK...women love it when you talk, tell her she feels great, whisper it in her ears, encourage her to do likewise. Most women love to talk dirty but are embarrassed to do so, as with all areas of being intimate, encourage her to drop her inhibitions and you will become the best lover she has ever had.
Properly pleasing a woman is the most rewarding thing in this lifetime!
