How do i get my girlfriend to get rougher?

I want my girlfriend to get rougher with me while we are having sex but she always says she is afraid she will hurt my pen*s, but its tough and I know she won't. I really want her to do this but she won't. Any ideas?

get her reely in the moment an den refuse to do it until she gives in
trust mi she'll b wild

but then all she wants to do is jump me...I need the mood first...I need tough things done...shes scared to do them. help..

sometimes it hurts a girl to be rough.

you cant really force someone to be rough they either like it or they dont

your funny.. all I can suggest is instead of telling people of fun advice, you tell her yourself, good job. and also.. it is somewhat her decision.

I have told her...she could use something on me to get rough, it doesnt have to be hers...mine just aches for roughness...she tried last night but was just afraid that she would hurt my pen*s, but I kept telling her you cant hurt it...but she still doesn't want to rough it up! I just don't know what else to tell her to get her to do it. Maybe I need to find somebody else?? I really do like her though...

It might hurt her to be rough with you
Get her in the mood make her want you so bad she has to rough
