Sometimes size simply does matter, however.  Gina from Los Angeles has this to say:

"I have been dating a man who I think is wonderful.  We have so much in common, and everything is great.  The problem is that when we have intercourse, I can't feel his penis inside of me.  There is also no contact with my clitoris.  It doesn't matter how long he goes, I can't feel his cock.

With other partners, I can reach orgasm within a couple of minutes, but he is so small, I just can't.  I feel embarrassed going on about specifics, but his penis is about 4 1/2 inches long and very thin. I try to tell myself that it doesn't matter, but the fact is that I deserve to have good sex and to have orgasms.

Not only can I not come, but I am worried that he can't feel much either, which makes me feel like less of a woman with him.  I don't know what other women do in this situation, but I'm confused and upset.  This guy and I get along so well, and everything is so great, but the sex is so unsatisfying.  What can I do?"

There are a few things they can try, but unfortunately first she has to be able to tell him what the problem is - and that is bound to be uncomfortable, and to put a strain on their relationship. Can you imagine how difficult it would be for a woman to tell a man she cares about that she can't feel his penis during sex?

After they have talked about the problem, they can talk about solutions so that Gina receives the sexual stimulation she needs to feel good about their physical relationship.  There are  penile extenders available at most sex toy shops, or they can be bought online. There are  small vibrators designed to stimulate the clitoris during intercourse or at other times.  Her boyfriend can use a vibrator and masturbate or perform oral sex before or after intercourse.

Also there are penis enlargement techniques and programs.  First off, there is surgery, but that is expensive and intrusive. Most men would not willingly undergo surgery, nor should a woman ask it.  Then there are mechanical enlargement techniques such as penis pumps and stretching rings.  These can have some effect, but can also weaken and tear the delicate tissue of the penis.  Some doubt that these pumps can be effective, and there are differing  opinions as to whether such mechanical techniques work.

There are also exercises like the jelq and some special kinds of stretching.  These exercises  can have some effect, but require both knowledge and regular effort.  Lastly there are penis  pills, which on their own usually have a great effect and can increase the size of the penis. It all depends on what   Penis pills you choose as some are simply a rip off.

Obviously in some situations, size can make a difference, not only in terms of the quality of  sex, but also as far as the comfort involved in the relationship.
