I need help please as I am not sure or my self esteem is low
Context
I met my OH 4 years ago
When we met , the honeymoon period was short lived as he had a Prostatectomy ( removal of prostate and had Radiotherapy). We broke up after 4 months due to a rebound infidelity which he told me happened ( otherwise I would have never known)
We got back together 9 months later and have been together since. Our sex life is completely non existent - last time we were intimate was 3 years ago when I was 46 and he was 52. It doesn't help that he is overweight which does not help in trying to build some form of testosterone ( doctor advised) and he will pay a personal trainer but will not be bothered. We cuddle at night before sleep ( probably 2 mins then a kiss ( peck and turnover and sleep). I yearn for intimacy esp as am still young. I spoke to a GP (male ) friend of mine who said most men who have had this procedure are unlikely to ever be physically intimate again
I spoke about marriage as I am christian and at first I was ambivalent but I feel more that I do want to . I spoke to him and he said he will make any form of commitment but will not marry.
What is upsetting me - He advises he is completely dead down there but stares at women!! If he is what he says then I don't know if I am being naive or looking at women , rubber necking ( turning your head even) to look at them when I am there - surely there must be some attraction. I asked him if he finds me attractive and he said definitely otherwise he wouldn't be with me.
I am attractive physically however I think my self esteem is so low as I feel rejected by lack of intimacy, lack of marriage. I feel he is having his cake and eating it . The whole sex subject is so uncomfortable as he shuts it down and I feel I am wasting my time but feel so low or lack self confidence to leave
Please advise
