not having erection while sleeping?

Hello and welcome to e health forum.

It is common for young men, who indulge in masturbation, to have such issues. But this common issue of lack of proper erections is transient and is mostly due to stress.

You should relax for now, and stop masturbating for a while, and indulge in other activities to take your mind off the matter. After some time, you will begin to have proper normal erections.

With regard to the size of the penis, I would like to let you know that unless you are in possession of a ‎micropenis - a rare condition in which a man’s erect penis is shorter ‎than 2 inches in length - size does ‎not and should not matter. ‎
‎
When measuring the penis dimensions, you need to consider the following :

‎1. length (the measurement from the base of a man’s penis to the tip) and

‎2. girth (the distance around a ‎penis, usually measured at the middle of a man’s penile shaft).

The average penis ranges between 3.5 and 6.2 ‎inches in length and between 3.7 and 5.1 inches in girth ‎when erect.‎
‎
In case, you still do think that your penis is very small, then consulting a urologist for a proper ‎evaluation and discussion of surgical elongation of penis can be considered.

I hope this helps.
