and it appears to not be logical and can never rise to the level of a scientific thesis. Even if the libido / sexual drive is high in such a person yet mental satisfaction is necessary in such a character. Such people look at the
innermost deep-rooted feelings and soul's yearning for spiritual perfection. Various other aspects prominent on the palm will direct the person towards a specific nature. If the person is erotic then he is likely to be be motivated to satisfy his urges not by the act but by the mental stimulation of any kind ; it could be written material or visuals etc.
The Individual in such case sometimes does not need a partner too to get required satisfaction. The highest levels of Consciousness can help them attain self satisfaction too. Kindly note here that I have just taken one aspect so the actual reading will be in relation to other accepts of the palm and not just by looking at this aspect in isolation. Human nature is complicated and nothing can be generalized. Note here that the permutation combination to this one aspect with other aspect will give a true nature of the person.
