I don’t even know where to start because I am in the exact same situation. Perhaps everything works out for a reason, because in order for a couple to practice true tantra they must practice the non-sexual bramhacharya for a few years first.
Personally, when I am fully devoted to my yoga practices ie. pranayama, hatha, etc… Sexual desire does not come up, and I am also 23, so it is possible. But when I change my mind by reading something or hearing something from someone with an animalistic mind, I may turn my attention to lower to the sex centre. This ignites a great amount of desire and frustration due to its unfulfillment.
The reason that it is not fulfilled for me is because I have a fear of dating. I am attractive and charming, and women approach me, but I am just straight up scared. I try to overcome the fear to the best of my ability. But it just has not worked out yet. It is very frustrating when the desire is there. When the desire is not there and I have been practicing my sadhana, there is no frustration, only power and a huge amount of energy. So much energy that I am so strong and powerful!
Practicing of prolonging will activate sexual desire even more. With the path that you have chosen, it sounds like you are very spiritually focused. Therefor I would suggest a devoted yoga practice. Google, kundalini tantra, and there is a .pdf file, by swami satyananda saraswati. This book will explain a lot. I am just reading it right now, and all of my experiences are making so much sense.
People will tell you, you are an animal. But, you are not completely animal, you are also a spiritual being. And the most important part of our evolution from animal to spirit is the sublimation of sexual energy.
It is difficult, but with true devotion and practice you can master your desires, and this is when you attain liberation. The thing is, you have already come a far way, because your desires are brought to the surface of your awareness.
I hope I explained some things. And I am sure I still have many things to learn. But one thing is certain. One can sublimate the sexual energy, transcend desire, and attain supreme samadhi and the awakening of kundalini. These people are the greatest!
