Believe it or not, men spend a lot of time worrying about sex and their ability to perform. It's probably one of the most important issues in the life of a man and it has profound effects on the general disposition. A worried man is a man whose sex life is not all roses or who thinks that he does something wrong, despite the fact that there may be no complaints from the partner. Some men actually spend a lot of time worrying about this or that and no amount of reassurance could put their minds at ease. So, as you see, insecurity is not something confined to the fair sex, but more of a widespread state of mind.
The top worry of any man who likes sex and wants to have as much as possible is the classic "Am I good enough?". This question has several meanings, depending on what the individual sees as a liability in his physical appearance or behavior. It can mean "Am I big enough?" if the man in question has a small or average-sized penis. It can mean "Am I attentive enough?" for the worried lover who likes to get the dining and foreplay part right. It can also mean "Am I giving her an orgasm?" since one of the big mysteries for men is whether women fake it and how often.
Which leads us to the next big worry. This one can be summed up with the nice question almost any man has asked at one time or another: "How can I tell if she's had an orgasm?". Unfortunately for the men, there is no way of knowing for sure whether the lady has had an orgasm or has acquired considerable skill at faking it. If the issue is really bugging you, then try and discuss it openly with your partner. However, unless you or the partner are dissatisfied with your performance, you should leave well enough alone.
Near the top of the tree lies the eternal question that millions of frustrated men have been pursuing without much in the way of results: "Does size matter or not?". And once more we are faced with the unpleasant task of saying that there is no final answer to this question. It all depends on the woman and her preferences. Some think a 6-inch penis is big enough. Some don't care one way or another as long as the penis is not too small, but, again, there is no definitive definition for "too small".
Then we have a whole bunch of problems that belong to the less experienced men. "How do I find the clitoris?" is a common question among the men who rely on intercourse to carry the session and are too embarrassed or too grossed up to go and explore the genital area. Steel yourselves, boys, there is nothing to be embarrassed or grossed up about. Nature has made us wonderful beings and worthy of each other's respect. And by the way, giving oral sex can be a fantastic experience.
"I'm still a virgin. HELP!!!!". You don't need any help, just some common sense. There is no deadline for losing the virginity and you certainly should not take unnecessary risks just because you simply have to have sex with someone. Have some patience, it will happen sooner or later and it's far better to save the first time for somebody special, than to visit the VD ward or fall in love with a person that does not care for you.
"She's more experienced than me! What do I do?". Enjoy the situation, of course. If she is indeed more experienced than you, ask her to teach you all the tricks (she'll be tickled pink by the idea), then start improvising on the knowledge. Pretty soon you'll have her amazed and you'll be in control, if that's what you want. Alternatively, you could slowly sharpen your skills, while enjoying every minute of pleasure from a woman who really knows how to take care of a man.
And, finally, we have another series of situations that make men uncomfortable: "She not ready for sex / anal sex / oral sex / fantasies". Guys, rushing in or being pushy about something as intimate and as important as sex is the worst possible approach. Keep your hormones in check and help her overcome her fears or worries. If you don't care for the soft approach, then leave the girls alone and find somebody else. Think about the day when all your waiting will pay off and she will say "Yes". That's something worth waiting for.
