nor read through all the replies to this topic so if i am repeating anything i apologise now but.......
much as i want to reply with is there such a thing as a bad fuck...... i will leave that bit of sleazyness fo another time and try and be a little more serious.
Sex has to be a 2 ( or 3 or 4) way thing, anyone, whether male or female is only going to get out of it as much as they are pepared to put into it. Obviously some have talents in specific area's ( i know a bloke who has never failed to make a woman multiple orgasm with his fingers) others have talented tongues some can fuck for england etc....
So if you think you are a 'good fuck' maybe its cause you have had the right partners.... and if ya come away thinking your performance was less than 100% maybe you had the wrong one..... just how I see it
