Yes. I have been trying to think of a way to explain why your questions aren't inappropriate when you are tryng to have the best health. Maybe "Lion King" and "the circle of life" is within your movie experience. If not watch it soon.
From the perpective of a teen, sexual attitudes seem contrary. Men are at their sexual peak at an age few are self sufficient, let alone able to support a baby and mother. Women are no different excepting they are hard wired to care for their babies and can't easily abandon them. Parents never forget how life changing a baby is. The most prepared parents are overwhelmed by the irrevocable responsibility of a life that will perish without full time care.
Because of the enormous consequences of a teen pregnancy we go overboard trying to protect adolescents who are capable of conceiving at 13. So, your 23 and ready for marriage and your pastor, preist or rabbi instructs you and your wife to be fruitful and multiply. In other words you must screw your brains out from now forward.
Like in "The Circle of life" one thing we share with all living things, an irresistible urge to procreate. Your parents and extended family have been watching you grow up and are excited at the promise you represent. Part of that anticipation is a grandchild but more so they want you to have every possible tool and advantage to blaze your own trail. They want you handsome, intelligent and healthy so you can attract the best life partner you can. This is being human.
You mentioned a certain fear of your father. Remember this for the day your son is chaffing against you and you chafe back with you manly body, emasculating him to a degree. We aren't wolf packs but alpha men and women lord over their children as long as they judge to. Or until a boy/girl earns or stakes his or her boundaries. Good parents, and I think you have some, celebrate your milestones like a low voice and body development.
Fifty years ago Masters and Johnson published "Human Sexual Response" the first factual study of our true sexual behavior. In spite of this best selling book and the introduction of "the pill" kids were already tramatized by over zealous protection. All girls were saving it for marriage which delayed sexual intercourse until 19 or 20 instead of awkward, rushed sex at 14, delayed by that trauma for a couple years before trying again.
Mature adults revel in the spark of youth because we understand that the physical assets and raging passions represented in you and others define our finest nature and the future of humanity. Libido in this context isn't evil or dirty, in fact it as essential as anything involving your health and wellbeing.
Don't create a problem to justify another. You want everything now! Instant muscles, miracle cure, an occasional nicotine habit, good tasing medicine and perfect poop. Healthy libido is like the young bull talking shop with the alpha bull. The young bull blurts enthusiastically "hey, let's run down the hill and mount a couple cows". The old bull salivating musk looks from the cows to his young friend and says "why don't we walk down the hill and mount 'em all".
You may just want a more developed body. I would have your T checked first. If you are low, it will not enlarge anything except that magic that rises with a thought. Building muscle bulk is hard work especially if you don't have much bulk or weight to start with. Any quick solution is fraught with danger like anabolic steroids.
