Male crickets have some of the most varied genitalia found in nature - no two male crickets are built quite the same way. I'm not talking size, I'm talking function. Some have little lips around their penises, some have little fingers, some have vibrating penises etc. The female cricket has a load of choices when it comes to sex. So, I figured, why not copy crickets? Think of something that would be stimulating that I can't do during intercourse and find a toy that does that.
For whatever reason, guys get to come almost 100% of the time and few women get that kind of payoff from sex. So whenever it looks like what we're doing naturally isn't going to be enough for her, we bring out a toy from our bag and it's almost always enough to get her to climax.
