Whats it feel like for a girl?

There was this one time when I was sooo turned on that I jumped my bf and I had him enter me before he was completely hard and it just didn't feel right....and he couldn't enter me very forcefully and it was just wrong! I had to give him oral to make him go fully erect and then have sex.....and that felt much better
so yeah the harder you are the better sex feels for both parties

Its better when he is, yes. Not as much that she can feel it, but knowing he's that happy would please her. At least it would me. =]

Usually I can't even feel when my guy goes limp. Especially when I'm on top. =] I think it feels better when he isn't all the way hard.
but when he is on top and trying to you know go in. Yeah its better if he is all the way hard =]

Yes it feels better the harder he is. No doubt about it. Plus it kind of ruins the mood if he isn't that hard because it is messing with her head as much as it is yours. Then it is just all messed up.

Yes. Unquestionably.

We can tell when things get a little less than hard, and it's pretty disappointing when it happens. Both physically and psychologically (even when we know it's not our fault).

As I understand it, the answer is unquestionably yes. There is however a downside to be said. It is possible to be "too big". If you go too deep it is possible to hurt her. Generally this limit starts at around 8 inches but its different with every girl. If this happens, try letting her be on top because then she can control the depth so that she doesn't get hurt and it feels good for both of you.
