to glossydong :No, it's just that everyday life and routine make familiar things boring. Do you know what is best pussy? - New one. If you ate one thing and only that one thing every day for years eventualy you would get tired of it, same with beautiful woman. Beautiful women is common nowadays. And new one much more exiting.
to Irmis888 :What real man is ever tired of fucking or worse tired of fucking a beautiful (far better a fit beautiful woman). The bf will have to be either crap at sex, not enjoy sex/low sex drive or possibly gay. The only other explanation is the gf is a nympho. But seeing as that is a rare thing or something that exist in fantasy porn - a nympho beautiful fit woman is up there with the tooth fairy! It is more of show me a beautiful woman and I'll show you a bf who can't get enough as shes too busy with her life & the constant attention/offers ๐
