No envy at all.
I understand the penis envy; no periods, cumming from penetration for almost 100%, and yes we squirt for almost 100% while cumming, when we're aroused it's almost for 100% visible, and we don't need to lower the pants for a piss, and no anxiety to be pregnant, etc...
Only a small percentage of woman is multi-orgasmic, but also a small percentage receives never an orgasm. (neither from masturbation, oral or penetration)
Then how many woman receive an orgasm from penetration alone? 50%? Maybe 60%?
So they may have a longer orgasm of a few seconds more for all the disadvantages.
If I could hold my penis and as supplement a vagina, the answer will be : hell no!
