In what position? I was touching my wife cervix while she was on top only at 5.75 NBPEL for 12 years, neither her or I liked it, we didn't know what to do. I was so excited to be back there that I just wanted to keep slamming it. The goal is that right when you get there, reposition! Now with my new gains both her and I are in heaven, it seems like to me that I am lightly gliding past or around the cervix now and both her and I go crazy. I feel it way better and am in control more when she is on top but now with doggy and missionary in cue for deep penetration, I'm on cloud 9. In other words she will love more.
At whatever size you are at, reposition and bang away.
I did a thread about being in Stealth mode and or telling wifey you are just doing this stuff for EQ and not for PE, they seem to take it much better when you say it is for EQ, they are much more empathetic that way.
