A balanced and perfect sex should have all the five sense in action if at all your a perfect human being.
1. Sense of touch, you should get the feel of touch from/to your partner - soft touch and that everytourch to a paricular part of the body pays back with an erotica action.
2. Sense of smell, it is known that, everyone has his/her own smell of which has the effect in common to human beings when exercising sex even other animals has this in action too.
3. Sense of hearing , the sound/voice has its part in the due cause, I mean physical groaning or what ever, and differs from one to another.
4. Sense of sight, its magnification of physical attraction to a seen object clearly far assimilated to imagination that never materialized to a perfect orgasm lather a ****ed one.
5. Sense of test, physical sex-intercourse justifies the real test to why should you morn, groan or keep silence- I mean hot, warm, cold, wet, rigid, heavy stroking, weak stroking etc.
I wonder how should somebody acquire a perfect and balanced sex via a phone whistle evolving only the sense of Hearing and imagination (feeling at the far extent)
ALL the best guys.
