Travis Kelce is opening up on what it's like to date the most famous singer on the planet ... saying the craziest part is folks watching his every move -- meaning he can no longer relieve himself on the golf course.
Kelce chopped it up with Will Compton and Taylor Lewan on the "Bussin' With The Boys" podcast this week ... when he peeled back the curtain on his romance with Taylor Swift -- and denied they're purposely trying to get more eyeballs on them with their adventures.
