I ain't no relationship guru, but being in a relationship that's now approaching almost double digit in no. of years, i do think maybe i'm blessed to have a little bit of qualification in this dept. Firstly, in the gay world of relationships, be prepared to have your heart broken, not once, but at least a number of times, before perhaps you learn not to wear your heart on your sleeve but instead choose to settle down with someone only if there's chemistry (and not merely the "physics", or shall I say, the physiques..haha). Second, all physical lust dies with time...accept it. What sustains a relationship is chemistry, inner beauty, shared experiences, warm physical touches, loving care and concern, and if you're fortunate to share the same faith in God, a shared spirituality (yes, you'll be amazed how much a spiritual dimension can bring out so much meaning and inner peace...so don't underestimate this aspect). All these can make for a truly meaningful, loving and lasting relationship. Your partner is your companion for life (not just sex). So go and talk to him for heaven's sake. If the bitter truth spills out, so be it. Better you face the truth sooner than later.. in that way you can move on and not labour under false hopes. Good luck!
