Swallowing

Ladies, I need advice. I do enjoy the act of oral sex with my boyfriend but when it comes to the act of swallowing I hesitate. I rather just get on top and finish it off. But my boyfriend has mentioned to try it and I want to but I’m just so nervous about it. I once tried it with my previous bf and it tasted horrible that I wanted to gag so I become scarred from that. Lol but his diet was poorly compared to my new man who actually eats fruits and veggies. I’m afraid of the texture or even the taste. I need advice to help me encourage doing it!

Thanks in advance!
