Normally,within a relationship, I would advise people to work on the relationship. Sex is not a priority in a relationship and you could always tell this partner what you want and how you want it. Is it even worth that much with your cuddy buddy? Some may be caught between taking time to mold their friends to their benefit while others may argue that you should simply move on and find someone else who is already skilled.
If you decide that you should teach them how to stick and move then go ahead. I don’t think I would waste my time trying to teach anybody I am not exclusively involved with how to get me off when I’m sure someone else out there knows exactly how I would like it done. You can’t look at these friends as your soul mate or significant other. You became friends with benefits for a reason and if the agreement between you two cannot be upheld then it is time to make the agreement null and void! Some might argue that they do not want to have so many notches under their belt. They might say that this may make them promiscuous or what not. Let me explain my opinion on that. You are what you believe you are and not what other people say you are. Sex becomes a problem when it is frequent, in exchange for something and affects your life. If these aren’t issues you face then don’t worry about how many people you have slept with, only worry about being safe. Now that that is taken care of, you need pleasure too! It is quite easy for a guy to have an orgasm opposed to a female and I am in full support of both parties leaving satisfied. If your friend’s benefit package isn’t satisfying you then it is time to shop around and check out the competitors packages.
