kegel exercises - can it lead to loss of internal energy (similar to how sexual activity and lustful thoughts do)?

I do kegel exercises everyday just for good general health, spending a few minutes to do a few sets.

Here's how I do mine.

I do it as part of my sleeping bag yoga sequence, so I'm lying down, totally relaxed.

I breathe naturally, relaxed.

In other words, I'm  not trying to coordinate breath and stretch it out to synchronize with the muscular contractions in any way.  If I'm inhaling or exhaling as I do the muscle contractions, I don't care, just focused on trying to be as relaxed as possible (passaddhi, pacification, kaya and citta body and mind). 

I'll at least 9 reps per set.

And I'll do at least two sets.

first set: I contract the muscles that would stop urination. I hold the contraction for a few seconds. The focus, like every other jhana and taiji or qigong practice as I do, is to be a relaxed as possible. The more relaxed you are, the smoother, more effortless the motion is, the more easy and smooth your breath is. 

second set: I contract that muscles that would stop defecation (excreting feces, taking a shit). Same process of relaxation as with stopping urination. 

I spend enough time on the exercise to feel like I'm improving, getting smoother, easier, or at the very least, just not getting worse (body getting tighter and more blocked up energetically).

Can this kegel exercise cause leaking of internal energy?

Not for me, and not the way I do it, with no breath coordination, totally smooth and relaxed. 

But someone with existing health problems, who knows? The body is resilient, but also fragile. Some energy channels getting blocked, and then with jhana charging up your battery to much higher power than you had before, weird things can happen. 

Some of the kegel exercises, and qigong in general that are IMO too finicky in trying to coordinate breath with movement, causes mental and physical tension, thus blocking jhana.

If you can maintain partial jhana (total passaddhi pacification of body and mind) while doing any qigong or kegel, or even western physical exercises like pushups and pullups and jogging, you'll pretty much be assured of minimizing internal energy expenditure or leakage.

Probably the biggest cause of internal energy loss is strong negative emotions like lust, anger, fear. Even if you don't masturbate, if you have lots of intense lustful thoughts, there will be internal energy loss, it will drain your jhana battery.

If you have no lustful thoughts, for example when I take a shower, I could rub my private parts as hard and as long as I want, there won't be any erection, no internal energy loss, no sexual fluids being generated because of the absence of lust.  

As a counter example, if you have strong enough lust, for example you're young, horny, not experienced at being celibate for long periods of time, say 3 months or 6 months, even a few seconds of exposure to very stimulating visual or even just thoughts of strong lustful intent can cause an ejaculation, without anything contacting your genitals at all.
