to start i always had no problem with my sexual apetite. i always love to have sex. but i passed on sex with my gf today becoz i felt the urge wasn't there. she says its ok but i know she was dissappointed. she thinks i'm losing interest in her and that i would rather have sex with our friend which definitely is untrue. we had threesome before and even swapping partners but still she's the one i really want to have sex with. i really couldnt beliv myself. how could i pass on the invitation to have sex. i may be very busy with work lately but that didnt bother me in the past. what do i do to kip the fire burning? hehehe thanks in advance.
