Why sex is considered as biggest obstacles for spritual growth in Hindu vedic tradition?

In this world, various kind of feelings and thoughts a human being can have. But sexual feeling is very much stronger feeling than any other feeling. In ancient time, sex was considered as biggest hurdle for spritual upliftment or for attaining siddhis from sadhana. Behind this consideration, various reasons are there. That's why sages, saints and spritual master were not marrying and keeping thereself away from female gesture. They alway avoid to meet Femine gender peoples and even not touching them. As mixing of any other color with black color, alway it results as black. Similarly, if there is sexual desire or feeling in mind, no any other feeling can replace it easily. Mantra has a particular meaning, on repeatation of which creat feeling in mind and on practicing slowly of that mantra siddhi (Success) is attained. In yogic practice, a yogi should have to concentrate on a single point, subject or portrait of god or goddess. But if any part of mind, sexual desire is there, then definitely that desire will disturbed practitioner mind and divert him from his spritul path. Whereever a practitioner's mind will go, their feeling will be generated and energy of human body will flow toward that and be applied to make truth of that feeling called as siddhis. In another way, it can be said, due to sexual feeling loss of energy will be caused. The sadhak should store energy and not to loss downward. Tantrik sadhak somehow uses strong sexual feeling during tantrik sadhanas and prevent to flow energy downward and use to press those energy to their spritual chakras to attained siddhis. But it is only for Tantrik sadhanas and not for vedic / satvik sadhanas. For Vedic and Satvik sadhanas Sexual desire and feeling must be prevented to get success in sadhana.
