Pre-net the methods I contacted WGs were newsagents cards, indirect and direct contact mags where I may of got a really bad photocopied pic of the WG that didn't show me what she actually looked like. For the indirect mags I had an accommodation address for many years where I also had my porn vids sent to me.
And my primary method was personal ads in my local newspapers and there were 3 at one time in my area. Met some good WGs over those years but also really bad ones. A difference with some WGs nowadays in my experiences is there were more what I would call amateur WGs about then, looking for some pin money, some of them were very flexible about the length of the punt and what they really did compared to what they said they did. So I may of booked for an hour but stayed 3 at the WGs invitation. Kissing generally wasn't on offer back then, the time of AIDS and John Hurts doom and gloom advert about it. Most WGs of the day said kissing was for their partners only.
This all changed when EE WGs started to come here in numbers, many offered kissing and OWO and for cheaper than the Brits, some of those Brits who didn't offer kissing started to when faced with the competition. I recall speaking to a Brit about this and she said well its either offer kissing or a lack of johns as she called punters. I said but you told me it was for your partner only, she said that was then, this is now, a pragmatist living in the real world. Bless those early EE WGs, they shook things up and helped my wallet plus I got more for my money. The one downside was loads of Irish WGs went back home, some of these were repressed catholics and filthy rebelling.
Even arranging a punt in my area could be a chore, I used phone boxes to ring WGs, problem sometimes was the phone didn't work, the box had been pissed or shate in or set on fire.
