I'd say stay away from all jelly toys, they're just not body safe, quality or made to last. As for other products I'd suggest the Butterfly Kiss, Bimini Flash or the Petite Couture Amorous (or any of the Petite Couture products).
I'd also be curious to know if you've ever had an orgasm,and if you did was it from clitoral stimulation or internal stimulation (or both). I ask because if you've never had an orgasm and are trying to achieve one, it might be better to go for a clitoral product since over 70% of women require clitoral stimulation to get *there*. If you have had one and internal stimulation was what got you there, go for a product that will replicate what you were doing when you achieved it.
