Hi, I 've been with my partner for a year now and everything was nice until a couple of months ago . He started to avoid having sex with me he always said that he was tired even started to make excuses like this one time he said he felt dizzy the next morning because we had sex the night before .BUt recently he told me that the reason he acting that way is because he feel unattractive . What can I do , what can I say to him to help him with this problem?
