It is perfectly normal to feel some nervousness or uncertainty when you first become intimate with someone. Poor body image, weak self-confidence or sexual inexperience can all contribute to this negative effect. Penis size, or a lack thereof, can create so much confusion and insecurity, even to the point of obsessiveness. It is useful to have SOME size, but more than a few inches doesn't make the difference between a good lover, or bad. In any case, you don't have to let it weaken your performance; you can pleasure the heck out of someone regardless of size.
We’re no longer living in the proverbial caveman days where a big penis dictates a man's virility, sexuality and masculinity; if it's connected to a vulgar, inexperienced oaf then he doesn't stand a chance. Although a big package might make your life a little easier, you won’t have much of a grace period if you have inexcusable sexual habits. Being a master in the bedroom is not just about deep penetration. It's about having confidence, openness and impressive bedroom skills - with emphasis on skills...
Some women truly don't even like a big penis – it can be uncomfortable or downright painful! Also, of much more importance to a woman is penis girth (measurement around the penis) rather than length; the nerve-endings within a woman's vagina end within a couple of inches, so the sensation of 'feeling full' is generally more about the width than anything else.
Work on your skills and up-sell them! Your penis won't be as big as one of her dildos, so don't bother competing! Why not become the master of cunnilingus and make sure to hone your fingering skills? Or how about turning into a walking sex encyclopedia? You'll impress her with your knowledge and dazzle her with your talent.
Maybe consider a massage course; it can make your partner feel so aroused and will help you appreciate the importance of touch and sensuality.
Feel confident about yourself – if she doesn't think that you're comfortable with your penis, she definitely won't be. The way that you feel about yourself is very apparent to women because they always want to read between the lines. Don't direct so much apprehension to places you're uncomfortable with; a man with a very obvious complex is a big turnoff. She might not have even noticed had you not obsessed about it.
Respect your sexual partner, whether they’re long term or not. This will translate to her feeling more comfortable and more receptive. The openness that she feels will actually improve her sexual experience with you (score for you) but she’ll be much more interested in reciprocating the same respect with inexhaustible invigorated effort. Score for you again.
Utilizing certain Sex Positions can make your penis seem like a giant's. Try integrating sexual positions that focus on G-spot Stimulation; they make use of the right angles and shallower penetration. Avoid the showy poses that even the most endowed fellow couldn’t handle. Also consider seeking out specialty condoms that are tailor-made for a smaller penis – when you need to call upon them in your time of need, you won’t be worrying about how they fit.
Tighten up some other areas of concern in your life so that you have fewer things to worry about, let alone what other people might think of your penis. Even just the action of self-improvement will change your self-perception. There are things you could do to procure bedroom approval: exercising to improve body image; having better grooming techniques like trimming or shaving your pubic area; good hygiene (smelling good & having fresh breath); and, preparing your sex space for maximum impact (even if that is only just tidying it up).
No matter what size you are (Average Penis Size - or otherwise), one thing is for sure. The biggest thing that your partner will notice is how much you respect and satisfy them in bed... honest!
