I know I was not being very informative regarding your question. I was only suggesting that perhaps if you looked around the forums you might find the info you require. I don't consider myself expert enough on the subject to offer advice to you.
From a personal view point I don't have an issue with a lady who offers CIM. Very few that I have seen offer this service but all the ladies I see have extremely high hygiene standards. I actually feel safer with these ladies that I would if I met someone who is not in the industry. You must remember that it is in the interest of these ladies to be extremely healthy because if they are not then they are losing money due to being out of work.
I also mentioned that there has been a lot of discussion on here about services being advertised but not offered when the client requests them - CIM is one of these services.
So while you might see it on their profile they may not actually do it.
On the other side of the coin I had an experience where I was receiving OWO from a lady who specified she did not offer CIM. I was not looking for CIM so I didn't matter to me. I had seen this lady a couple of times and each time was different with her which was great.
On this occasion while receiving OWO I knew I was about to cum so I thought I better warn her! She ignored me and kept going. I tried again to warn her but it was to late.
She looked up with a smile on her face — I said "I didn't think you did that?" at which her reply was "Only with clean people who I trust and know"
So, you can never be sure from a profile whether a lady actually offers CIM or not — some say they do but don't while others say they don't but actually do! It's a catch 22 situation really.
