OK, Flower, lets talk facts.
You are 'driving yourself mad' as you said in a previous thread....
I have intentionally put off getting too specific because I feel that you need to reflect on what you really want in life.
1. You get all hot and bothered when your b/f talks to other women.
2. You get upset when the subject of sex is brought up in a conversation.
3. When you call him, you expect him to drop everything and irritated when he has a business phone call at work.
4. Deep inside, you also feel that he asks too much of you when he wants to experiment sexually.
What would you think, and even suggest to someone else when you read your threads. Think, if someone posted the same situation as you did what kind of bells would ring?
It is my opinion, and please correct me if I'm wrong, that you are so darned insecure that it hurts. I certainly would not want to be in your shoes - and I'm sure you are uncomfortable in them yourself.
Yes, you are driving yourself mad... Stop this and talk to a professional about why you don't have confidence in yourself. You are so insecure that it's going to drive him away. If you really love this guy, then do both of you a favor and get to the bottom of your insecurity and learn to grow into a person who understands herself enough to be able to trust and understand others.
Why do you not accept it when someone tells you he loves you? Why don't you think you are just as good in bed as any other women can be? Why do you think your b/f talks to other women on the phone while at work? Until you have the answers for this, you'll continuously have problems in any relationship you start. Your own insecurity is going to drive you mad!!
Somehow, you have the wrong impression of a 'couple'. There must have been something very traumatic in your past that you have not worked on yet, and it's preventing you from having a satisfying life in the present. And until you straighten this out with yourself, you'll not have any peace in the future.
If you cannot or will not talk to anyone about your past, PM me and we'll work on it. I know from personal experience that a past that has not been 'closed' can cause unbelievable damage and am offering you a chance to at least open the door and work on the real you.
You deserve to have a fulfilled life in the present and future, so please take the opportunity given.
I want so much for you to look forward, and have your dreams come true.
Think about it, and get back with us. We are here for you, so grab that chance. It's free.

You want to trust him, but something is preventing you from doing so, and that is deep within you. Let's find out what that is...
