How to squirt?

I used to be able to make myself squirt when I was younger (16-17) and it’s happened once during a one night stand (19). Now I’m 24 and been with my hubby for 4 years and I just can’t do it! I don’t know how I made it happen before or why it won’t happen now. It feels so good and I want to be able to feel that strong intensity again and hubby wants to be able to make me squirt too. Sex is crazy good, we’ve tried toys and crazy positions and I just can’t seem to even get there.
