My partner and I have been together for 21 years - and we are not still together just because it's comfortable or it would be too difficult to divide community property or that sort of bull - we are still together because we both actively wish to be. He is a total top, and I mostly top - and from our second date we've had an open sexual relationship. He knew my libido was more active than his, and he also knew that my tastes in men were broader and my range of sexual activities far wider than his. We've enjoyed three-ways together, group sex and sex parties together and have each played alone many times when the other is not available (he works nights - including Fri & Sats, I work days...). We never play apart when the other is available and don't take away from our time with each other. Since he has almost always been busy working Friday and Saturday nights since we got together, I have played either one or both nights on a weekend most weekends for these past 21 years. He's actually happy I'm not sitting home bored, and knows that I'm not seeking any other emotional relationships. He's also a voyeur type (not my thing) and I an exhibitionist, so even when we go to sex parties together, he usually shoots in 15-20 minutes then watches while I play for another couple of hours (and he maybe reloads). It has worked for us, but you neither partner can have a jealousy issue!
