help me out here ladies

Migi
Okay so oral sex. I go down on him whenever because honestly I love it and when it comes to sex I feel like I'm on top of the world but when he brings up why I won't let him go down on me I freeze up. I tell him I'm just not into it but tbh I get self conscience like what if he doesn't like the taste. So I need some advice how did you guys break the ice with this.
