ok ok me and my girlfirend have been having sex well we did for the first time like a week ago then once more yesterday,now when I finger her I feel this like round thing in there like up in there I dunno wut it I havnt felt it before until uyesterday is that her cherry and how come I never felt it before???its about the size of a nickel I dunno wut it is but somone please help me so I know wut to tell her wut it is lol cause im not sure she even knows lol

what your feeling is her g-spot...

it could be her g-spot or her cherry if she is a virgin mostlikly her cherry and you never felt it before because she was tight

okay if you and your girlfriend have had sex then more than likely you have popped her cherry unless u'r not big enough I'm not saying you aren't I'm just saying. Or. Most likely it is your girlfriends g spot I am pretty sure that is what it is I hope this work
