I have some thought on this issue. Now my personal experience has been a double edged sword. Since my size increase my wife cums way faster and WAY harder than she used to, to the point where she just has to lay there without moving for about ten minutes after sex which is awesome!
However lately I have only been able to go balls deep in two positions her in top, or her laying flat on her stomach and me behind her. In these positions I can pretty much get All the way in however, if I try to go too far or push really hard (which I like to do) it hurts her.
So last night when we had sex she came very very very hard so I figured she was really warmed up and rolled her onto her back putting her legs in many different positions (in the air, wrapped around me, curled up to her chest etc…) now when doing this I could barely get 1/2 to 3/4 of my cock in her no way in hell I was going all the way in. Had her switch to doggy in which the same situation took place. When I came I pushed in as deep as I could go and I could tell it was a bit painful for her.
Every time I have grown she has had way better, harder, longer, wetter orgasms than ever before but it has been slightly detrimental to me just being able to fuck her super hard….
Also another important issue that I don’t think has been discussed is the women’s state of mind. My wife’s overall sex drive has been pretty dismal as of late. (Think its becaus of birth control) but it seems as if she is holding herself back from really letting go and just enjoying sex, as she does have some fairly bad anxiety issues and was raised in a very anti-sexual household. I think if she was able to just let go I could go balls deep no problem, but she seems to tense up and is almost “expecting” it to hurt… Hmmm maybe I should start a different thread for this topic haha.
