I'm not one who has ever had this problem. Well, maybe a few times, but this said, I have never had a problem with "silence." The old saying is very true...silence is golden...or it can be. I do realize that sometimes silence can be absolutely deafening! Especially when the two of you are new to each other, are nervous and worried about making an excellent impression on each other. And, you, or both of you, are also worried about saying the wrong thing or being.....heaven help us...boring.
I'm not one for idle chatter and in many cases would prefer silence. I've never understood why there is a need to be constantly talking. Being connected with a person is a lot more than just talking. I am a very tactile person and love to be touched and to touch. A hand on the arm or shoulder, the use of facial and eye expressions, a smile or laugh, can sometimes relay more than words can.
Always be polite, and always seem to be interested in the person and what they say, even though maybe you aren't. Even if you find the person not to your liking and believe the connection will end after that date....always be polite and never let it seem that you are disinterested or bored. Leave them thinking that you found them interesting and that you had a good time. Don't worry, if the karma was not there, they will know if the feelings aren't right. Hopefully!
People like to talk about themselves. I always try to equalize the talk about the both of us...give some info and then ask about them with a questions that requires more than a yes or no answer. It is amazing how much people like to talk about themselves, even when they say they don't.
Of course, when you get to know each other well, you are comfortable and other feeling take over, there will be no need to talk....maybe some moans,
yells, squeals, or a few well placed words of encouragement or of sexual joy! But them, let's hope we have gotten to that place, none of us will have to worry about talking or silence any longer!
