Just do what most stinky bandmen do and text a dick pic with the phrase "Chinchin Binbin"

I thought エロ meant erotic.

エロ  the plain meaning is erotic, but it also matters in how you use it tho.

I guess you could translate it somehow like this. 

Japanese bodybuilders are always so erotic💗.

Japanese bodybuilders gives me always a dokidoki. (dokidoki=heartbeat)

Japanese bodybuilders give me always  a wakuwaku feeling. (wakuwaku = horny)  

Japanese bodybuilders are always so hot   (Hot as heath hot, so 熱い)

Japanese bodybuilders make me always feel muramura  (muramura  = horny

Then people understand that a Japanese bodybuilders turns you on 😘

But my male friends... they use often "sexy"  or "yaritai"  if they feel horny.
