when my gf and i do it.. it feels good for her like only 1 minute [if she's lucky] every time we change positions. like we'll be doing it.. and she likes it a lot.. then after like 1 min she says she feels nothing. and then we'll change positions and she'll feel it again.. when she is like.. REALLY horny.. then she feels it all the time.. but just normally she doesn't feel it for more than 1 min.. and she only gets horny at night time.. but we see each other in the day time mostly. i mean it's her body and if she doesn't have a problem with it then that's fine.. but i was just wondering what your opinions on this situation were.. this happens with all condoms because we've tried 3 different kinds.. help plz
