Well... Buy some lube for her and a bite apple to strap on her mouth if shes complaining.. as for other stuff, yes you are young, and damn for a first cycle.. but seems to be going good.. so some basic checks
Are you doing HCG during your cycle? If not you need to 500iu 2x week then 1000iu first day of PCT
what is your planned PCT? you need nolva and clomid IMO. Esp for using tren and deca you need strong PCT!
do the test a week longer than the others, so ur off that last.
You can be having some de-sensitization due to higher amounts of the 19-nor version of DHT, which is less powerful than natural DHT at boners, as you can obivously see with the sides of limp dick. Can get it hard but still a softie, mainly due to the 19nor's DHT. Since you are still able to get a solid erection *im guessin* that its a sensitization problem. That can actually be attributed to higher DHT in ur system. One thing this does suggest is that the OP has a high level of 5-alpha reductase. So im guessing that he also has a full beard, and is relatively hairy. along with male pattern baldness in the family. *hey OP if im right can u reply / :-)
ALso, the progestins might *guess* be having some estrogen like effects on libido in a male (basically bad). I would go with a majority of the first and minority of the 2nd :P
No, its good that the 19-nors are higher than/equal to test because thats what you want to bind. You dont want to upregulate alot of AR receptors with test and the 19-nors and have them both bind which lowers the purity of the 19nor's binding whichs lowers their gains. The whole reason doing a 19nor is for their 'extra' benefit. And normally you have more progesterone in ur body, so when you cycle with test, progesterone also gets inhibited. Well if you are going to run a 19-nor, aka progestin, aka acts like a progesterone in the body where applicable, and can increase prolactin if estrogen is too high. Seems since he has a high 5-alpha reductase activity, and *hey OP are you taking a AI* and low aromatase activity. Also, Progesterone is known to regulate estrogen, and progestins mimic progesterone at certain receptors running the 19-nors at a higher dose than the test matches human physiology better which minimizes sides. Running too low or too high of a 19-nor will create menopause symptoms. Think of it, menopause is low estrogen (so if progesterone/progestin regulates estro) and you have low progesterone/progestins you actually have similar symptoms as low test/high estro which can be confusing because then you start a AI and it helps some *due to some of the sides were being enhanced by estro* but still there, then guys who run a higher 19-nor than test dont really have many problems nor sides. If stacked properly you should be able to do Test base, 19-nor, DHT deriv for a pretty advanced stack and with proper amounts you can minimize sides and use of AI's and etc. This can be achieved by listening to your own body and for faster, more noticable changes is to do Prop for a first cycle...
ok but now i am rambling lol, ive been meaning to write about that, but ive been procrastinating my masters project thats late but due wed but really the degree has nothing to do with my future... soo.. .lol hard for motivation :P
anyways i think i veered far away enough from the OP original topic...
If you want i can start a basic thread/or someone else can to discuss anything that i have said above in a topic wise discussion.

good luck play safe! and again, DO A GOOD PCT!!!!!! U need HCG!!!
