Tips ??

I have NEVER orgasmed before, which obviously isn’t great even though sex (and other activities) with my boyfriend feel great I’ve never achieved it. I have tried to get off on my own before but it never feels nice for me and I’m not sure how I can make it feel good? My boyfriend has gone away for 6 weeks and I bought a vibrating toy hoping maybe I could work on it then so I could achieve orgasm with him when he’s back. I’m just wondering if I could get any tips on how I can achieve it ?? Xx
