Problem being close to friends

I am looking for some insight into a problem that I have always had. I find it difficult to make new friends because I can't be myself and feel inhibited with them. I used to be quite shy but overcame this but would like some new people in my life. Strangely I don't have this problem with boyfriends I am sleeping with but it's very difficult for me to date men without sleeping with them as I feel really awkward and clam up. Would love to hear any ideas of how I could overcome this, thank you Should also mention that when I was young, my mum and grandmother were both very cold and critical, that might have some relevance:-)

I know how you feel at times but my problem was due to incest when I was a child, I went to therapy and now I am who I am and accept things in the now. Just try and not clam up and be yourself and you will find people who like you for who you are not something fake. I wish you all the best.
