My view of Dee is this, she has a problem with an addiction to a drug of some sort, anyone with an addiction inevitably put the drug first over everything family, friends and health. As a punter you know that anyone that doesn't look after their health will be a risk. My personal view of those with addictions are that, before their addiction they were probably empaths and sensitive / naive. I think Dee has a good heart, and that she's never let the addiction get too far get out of control, if it had I imagine she would be far cheaper, barebacking and doing a-levels or whatever she doesn't like etc. Not that DT and swallow is without its issues.
I used to feel a little guilty initially, but now I don't feel guilty at all because I know, like most us, I am a good client, who is friendly, treats her with respect in that I don't do anything she doesn't want to. I feel more guilty when I see a young Rom or Thai, in those meets it seems as though they aren't choosing to escort, and don't enjoy punting with you no matter how nice, and how much money you give them.
Also I started using a condom for my DT blowjob only sessions with Dee, safer for everyone, but especially yourself knowing Dee's services and drug use. Covered I leave the meeting not worrying at all.
