Modest and in a dilemma

So my man had talked about a fantasy of making me squirt during sex.. Not knowing what that was I looked it up and was taken back because anything I've read said I have to do this to myself first before he can .. But that requires toys of which I've never owned .. I told him and said I won't touch them until we talk about if your ok with me doing that .. He never answered on that .. Anybody have any experience with this during sex ? How do I relax enough and how can we achieve this together for my first time
