He is ticklish/sensitive to touching

Ok. Here is the deal. After being with this man for 3 years I have gone from being terrified, to disgusted, to curious, to intrigued and finally to fantasizing about giving him head. Never done it before. Honestly I wanted to try about a year ago, but when I started moving my hand down there while making out, he laughed and hit my hand away and said it tickled. I tried it again, with a harder touch and at his lower stomach, again, he made me stop. He thought I was doing it on purpose and got mad at me. I have never had much confidence sexually. So that night shattered me. It had taken me a while other year to want to try again. But now I REALLY want it. I get off on just thinking about it. I was trying to be coy about things and started moving my hands around his body. Same thing happened. He claimed he was too ticklish. Any tips or advice or anything so I can do the deed? I KNOW he wants it. But he, at the same time, stops me from going there! 😫😅🙏💦👄🍆
