I assume you are asking the difference of how it feels between fingering and fucking or sucking. It all has a different feel. I love oral and being eaten out for hours on end. Nothing like the feel of oral. I love being fucked. I assure you I know the difference between being finger fucked or fucked with a cock or even a dildo or other toy. I love them all. A woman can never explain how sex feels to them other than how nice it feels when done right or how much it hurts if done wrong (such as being fucked while too dry). It is like asking me to explain how birthing a child feels. No man will ever know the answer. It just isnt possible. For me I love sex and being fucked in every way possible. There is differences in how it feels when done by different partners. Some are more gentle while others are extremely rough. My suggestion is listen to your lover. She will tell you how it feels. Enjoy sex and know she will let you know if she needs you to change it up some how. Women love it as much or even more than men I assure you.
