I know this thread is a few days old but my take on it.
The numbness will go away, for some it takes a very long time others is happens fairly quickly.
For me it happened fairly quickly and I wish it didn't TBH.
I had a little pain that ended up going away, soon pain turned to nothing but a normal feeling.
As for orgasms, as much as I saw it as a vagina I also saw it as a "wound" and touching it worried me, the last thing was somehow this is to be used for sex.
It wasn't until about 12 weeks later that those thoughts started to change, I started to think of it as a vagina everytime I saw it.
I started to play around, I learned what I liked and what was working, I didn't orgasm for a while but when I did, boy it was great.
I'm now a very sexual person, I understand the power it brings and the enjoyment
