how are you defining sex??
for me 'sex' is anything that is intimate from a cuddle to penetration and many other things besides.
As a man yes i love to cum/climax and bring my partner off too but i love all those other forms of intimacy too.
if you're talking about just penetration then yes as a top guy in a gay relationship i'm up for that with my bf every day at least once a day and mostly thats how it goes/ends up and my bf has a high libido too. We rarely go more than a couple of days without penetrative sex.
But if either of us is tired, its late, need to be up early or a million other things, then a kiss, cuddle, hug, spoon and falling asleep together can be equally satisfying, albeit in a different way, and is just as bonding, reaffirming etc of our love.
