Temporary length gains during orgasm

I noticed for a while now that every time I orgasm, during the orgasm (or ejaculate, as both happen at about the same time), my penis seems to grow a tiny bit more than normal. It seems to gain at least an 8th of an inch or more. It stays this length for a good second, before dropping all the way down to flaccid. Does any one else notice this?

So far I can’t properly measure myself during this growth due to the tiny time frame and the fact that I have other things on my mind at that moment. ;)

Also, first post. :D

Yes, that’s normal, as you are contracting your BC muscle to push more blood in.

I have experienced this as well. It seems the more intense the orgasm the little chap will grow about 4 mm. I need to strengthen my BC muscle more.
