RE: looking for mature escort
You could try Private Sissi, they sometimes have ladies in their 50's and 60's.
Just call 732767448 or email at email@example.com and be sure to organize the meeting at least 5 days in advance because the girls change often.
If you speak Czech just buy an Annonze newspaper somewhere and you'll find some mature ladies in there. If you only speak English or German it will be much more difficult.
