So everything else is great about your partner but sexually they don't live up to your hopes and expectations, maybe they're selfish, sexually limited, physically incompatible, lazy, don't enjoy sex etc. Whatever the problem, there are warning signs about your future sexual satisfaction with that person. I have a friend that ignored early signs of sexual problems but got married anyway and remained frustrated since. Personally, I'd rather end it and try to find someone more sexually compatible even if it means being alone for a while. What would you do or what have you done about lesser lovers in the past?
