Problem in my private life with my girlfriend - please help?

we get on really well and the romantic bit is great as well. But what i cannot do is... (please remeber children may be reading so i will write accordingly) .. reach an "Organism" when i am inside her "Regina". "aural" and everything else works fine - but she would really love me to reach that point when we are "lovin' it" in the classical way. Funnily enough she reaches that point again and again until the neighbours complain about the noise. please help!
