There are a lot of unconventional ways to increase testo that can be brought up. Why not? Speaking to attractive girls will boost your testo, yes, just talking. It's easy, just anytime you are outside, say something nice and start a conversation. It doesn't have to be something about their appearance or you trying to rizz them, etc., just talk.
You can also do sexual qigong, edging in praxis but with a twist, look up Mantak Chia. Of course, lowering stress is a big factor, so take any chance you get to laugh and be jolly. When you are in the gym, lift heavy weights, fewer reps, more weight. When you have done a good sesh, celebrate. The act of celebrating will increase testo. You can do this at home to celebrate by lifting your arms up and feeling it, linger in it.
If you want entertainment, watch sport where your fav team wins. If they lose, you'll lower the testo. Have a meaty and fatty diet, I recommend five eggs a day. It is worth mentioning again the most important thing, which is sleep, so do yourself a solid and toss the phone or whatever else is keeping you awake at night, and go to great length to sleep well.
A critic could say that all these are short-lived boosts of testo. The response to this is simple: a change of action that consequently contributes to a chain of other actions that works towards the same goal over a period of time will have a cascading effect.
at this point it would be well off to mention that there is a whole group of hormons that ought to be talked about called the Androgens; and how they effect testo. GLHF!
