Id say it definatly just depends on the mood, if it was just that good sometimes, and maybe he wants to please me a little more sometimes hes coming right back for more, other times though even if im not finished he is! I wouldnt be offended at all, and in the 'recharging' sense I think men and women are a lot different, even if a women isnt in the mood she'll still have sex with her lover, but the man really has to be in the mood to do it, or I think it just doesnt work out too well. :)
