There is not a less crude way to say this so I hope I do not get this trown out.
Picture the last 5 sec before you ..... Now do you like to proceed slowly or w/ the same continued speed and pressure. Thinking of my H it appears that the big "O" is a time that it is necessary to slow down and proceede w/ caution or it is not to comfortable.
Well it is the same w/ us ladies. Keeping up the same pace is not very comfortable after or durring "O's". If that is lacking clarity illegal feel free to PM me and I'll elaborate in less lady like words. You never know the age of readers here and I'd hate to scare some innocent individual.
