...It's my experience that they seem to get closer to rock hard and stay there longer.
Glad you added the 'my experience' part. A downward curved penis gets as hard as an upward curved one, it just points downward (you know, like it says in the name :wink
so you might still think it isn't hard, but if mine is anything to go by they can get
and stay as hard as the next cock.
It doesn't help that a lot of pornstars with downward curves seem to pump them or something so they end up having to thumb them into a pussy (Shane Diesel seems to be in constant semi state, so much so that he even has to squeeze out his cum
).
...I think a downward curve works best at hitting the g spot when used doggy. so maybe a u works better from the front?
I know in my experience I can count the number of times my partner has had a vaginal orgasm from the front on one hand. On the other hand (see what I did there? :biggrin1
rear entry positions (either me or girl on-top) have resulted in more than I remembered to count so I'd say there is some truth in your statement.
The reason I wouldn't want to trade my downward curving cock is because of positions like these. I'm not saying someone with an upward curve couldn't do them, but with my curve they feel so natural for both of us that we quickly forget about how ridiculous we probably look and just work ourselves into a nice sweaty frenzy of grinding, heaving bodies (it is VERY hard to cum in these positions)
