Yes, sporting a mustache has been a problem with about 50 percent of the ladies I have visited. I also keep it short trimmed. I try to judge by the reviews which girls are OK with this. Best so far has been my recent visit with Amanda. Appreciate any info regarding their likes or dislikes.
Also on the subject of what the ladies like. When participating in the blue toast, always rinse for at least 10 seconds. They take notice of little things like this. Another is when they ask you to wash your hands. Again no quickies, take 10 to 15 seconds, they are very serious on good hygiene.
