Can’t orgasm...

I was married for 11years, now divorced. I’m dating a great guy now and we are talking about marriage (pretty sure he has the ring!) and we are in the process of buying a house! I never had a g-spot orgasm with my ex, but have had several now. OH MY WORD!!! Anyway, the only way I was ever able to have an orgasm before was with a bullet on my clit. My ex was lazy and said I have a small clit and gave up trying to get me off himself so... My guy now wants to, but it’s frustrating for both of us when it doesn’t happen. He wants to keep at it though 😍,he’s pretty determined! I guess I’m just used to the power and speed of my bullet? Any suggestions/advice?
