why is so hard to fufill a sexual fantasy?

Most men and women find it hard to fulfill a fantasy because of their insecurities with themselves.It may be that you have gained weight after a pregnancy or just have lost weight and you may have lots of stretch marks that seem very unpretty and in areas you are uncomfortable with. like your stomach, breast or thighs. Those are the main areas your mate will see when you get undress for sex. So if you are not comfortable with your body then you want be able to react to the fantasies you have planned out. Because your mind is on how you look and your mate's mind is on how you preform in bed. We just, people ourselves get caught up in the t.v. and magazine world on how you suppose to look when in reality those women are not that themselves. 80% of women have body issues so that's something we will have to overcome to have a great sexual relationship with our partner. I found it easy if this is your first time and you feel a little scared you should try to buy a sexual outfit that covers the area that you are shame of showing your mate, until you feel open enough to get undress with out the fear of doubt in the back of your mind. And another thing i found helpful is to get your hair and makeup did because if you feel pretty in the face and hair everything will overcome. If you have problems with other things such as what will my mate think if i want to perform oral sex on him or her. My reaction to that is, do what you feel is comfortable for you. If you think it's something you want forgive yourself in the morning for then don't do it, but on the contrary if you and your mate think it's something you both wanted to try for a while and you are comfortable with them, then take that experience and go with it. The worst regret in life is to not do what you wanted to do and it's to late.
