I need help from mature men and women!?

Ok how do I start.. well I have been married for 7 1/2 years with my husband. I have always loved giving him and just recently I tried swallowing his ***. It was pretty hard since it was my first time doing it and as hard as I tried I could not swallow it just to think of the taste and the consistency of it made me want to gag but, thankfully I played it off and just went discreetly to the restroom and spit it out and rinsed my mouth. That is why I wanted to post this question since I need some advice from people who have experience to give me some tips on how to improve in this technique. Since I love to surprise my husband, and he seemed to love it I want to get better at it. Also I am very opened minded so if there is other things I can do to spice up my life please feel free to let me know. Thanks
