Easier - your more relaxed, you know what you'll be getting & if you are like me, you can last longer.
The fluffy bit, well you can still keep the relationship professional, even if you do get quite friendly with the girl. I saw 3 girls over several years, they all knew I saw other women, one was always keen to find out what I'd been up to since I saw her!
This is very true. I've always tried to be friendly towards any WG I've ever met and am still on friendly terms with at least a couple of now-retired Regulars.
It can be easy for that to slip over into Emotional Attachment, if both of you aren't careful. I'm fortunate that I told one of my current Regulars about my case of E.A.S; and, although the current Regular and I get on really well both during, and between, meetings, we're both certain that a friendly but professional relationship is by far the best way to go.
