I feel compelled to advice u, not dat l know much but l think l can help. Losing urge for sex could be a result of several factors:
1.He may be depressed over an issue in ur relationship. There may be a silent issue that shook his emotions towards u;
2.He may have health problems, especially around his reproductive operations;
3.He may have gone thru an abuse or betrayal which something in u reminds him of;
4.He may be punishing u for some offence which u unknowingly committed;
5.He may be involved outside or became afraid of not satisfying u'
6.He could be spiritually manipulated & cant explain why d loss of urge.
Anyhow, reporting to friends & family is wrong & may drive him more into his shell. See a good marriage counsellor & fight to recover ur marriage. Dont give up on it, if u lose this, u can as well lose any other thing. Fight for ur own. May God help u.
