for the sake of further insight and discussion; when "fantasizing" about my S/O and being aroused by that, its not necessarily fantasy. its recalling instances such as waking up for work, still half asleep and waking my partner up with oral sex to say goodbye as i leave. him waking with a long deep breath and moan of pleasure, grabbing my hair and thrusting himself into me until reaching climax then simply leaving for work and during the day looking forward to returning home later that evening to finish what we started. its the little spontaneous things that turn me on and the anticipation of what is yet to come. if being together that evening is not possible, the built up excitement then becomes the mental stimulus for pleasuring myself.
