I actually indulge in all 3. My order preference is #1 mouth #2 front #3 back and no cim an no cum in eith hole due to wrapper but reachi9ng orgasm while doing Greek is Superb!!
For me, it's a nonissue unless I'm doing it sans cover with a woman other than a Provider (wife, gf...). If I do indulge in "hole tour" I start in the mouth, plunge some meat in and out of her pussy, back in her mouth, back to the pussy, ease thru the back door and finish up dangling it over her open mouth.
