Ice is another big player in oral. I can understand how some women can gag. I've known women that can drink cum like a soft drink. It's not always about swallowing. If you use your fingers, a toy, lots of saliva and work the penis you can get most healthy men to cum within 3-5 minutes. It's fine if you don't swallow ladies. It's not a must every time.
Ask your lover to go down on you after he cums inside you. If he wears a condom, take it off him and spread his love juice on your belly. Rub the cum on your inner thighs and ask him to make love to you again this time starting with kissing. All the way down your body. Making him taste himself. Any good man would not even hesitate. Just like if he asked you to taste yourself after you came. Finger yourself, use a toy. Cum and then take two fingers and enjoy yourself. It will turn him on to no end.
Our problem is we don't think past our comfort zone. We think the same old is fine. If your happy with that great. I hope your not because your here on LG. you want to learn. You want to experiment. Then do it!
