I have also been going through this and have been going through it for years. i really need a womans advice and would like to know if things have gotten better for you and your partner. I don't understand why I'm going through this because I have never had any complaints about my sex and I aim to please and always make sure the woman gets hers before I get mine. I don't finish until she gets at least 3 or more O's which I have given 10 in one night before. I have had women tell me that I was very good in bed and that I'm a man that loves to please so I'm a bit confused to why she does not want sex with me. Your feedback is much appreciated...I am going through pretty much the same thing as you! It's so frustrating, isn't it?
I'd like to chat more with you about how you're working your way through this and maybe we can exchange tips and advice and help eachother out.
I'm also feeling like I'm getting to the point of wanting to look elsewhere but really, solving the problem and not wanting to look elsewhere is what I really want. I'm sure you do too.
Best of luck, hope to hear from you sometime!
