I went to a Pro Cuddler who her entire apartment had incense and it smelled really bad. I only booked her for an hour session and the incense gave me a headache.
Smoke lingers... Maybe she went out the day before that happens. But I would mention it. I do not like smoke myself.
As a pro-Cuddler, if you do smoke, be considerate and take a shower before your session. I would hate to make a buddy feel uncomfortable because of any smell I carry with me. And it's ok to let them know you are not comfortable with that, they will understand and be more careful in the future
I think the key is to be honest in your profile. Don't try to hide the fact that you smoke. Then your cuddle partner or client can make the best decision for them. The assumption is that you will shower, but really sensitive people may choose to either not see you or book an outcall as a solution. I did a meet and greet with a Rover person once whose profile said non-smoker, but who it quickly became apparent she smoked. I had to wash EVERYTHING when I got home. Was just a waste of everyone's time. Better to just be honest.
