Well, I find personally that stimulating my g-spot is the most effective, even though I am still an-orgasmic. Up until recently, I've used my middle finger to stimulate it, because I'm unable to buy any toys(small house, snoopy mother). This can be troublesome because my finger can only take so much before getting tired. But one horny night I was searching for an aid in this predicament and there was a sudden epiphany when I noticed my $3 umbrella was sticking out of the closet, the curved handle was perfect, I still haven't reached climax but I've gotten as close as I ever have!
This is inexpensive and fun, you probably already have it! Remember, always be safe and clean up!
