1. Agency girls tend to be higher quality than indies but you'll generally pay more and often a lot more. Even agency girls can provide a poor service. Typically outcall based appointments.
2. Vivastreet is as reliable as any advert. It can be very hit and miss. You will find a lot of Romanian girls -they are generally considered to provided a poor service and falsely represent themselves. Adultwork is useful as you can generally see more pics (including verification pics
- you'll see what I mean!) and there are reviews of the girls, although this site is much better for an honest review. Watch out for Private Gallery scammers on AW - inviting profiles with no phone numbers.
3. Outcalls have the advantage of you not putting yourself in a risky location and some of these girls provide incalls in the parts of towns you might not ordinarily visit. Also, there is the advantage of not having to get dressed and travel home. However, I would not recommend doing this unless you were certain of the girl's reliability and quality as you are giving up a large part of your anonymity, flexiblity and security. If the girl is a B&S (see below) or her photos are 10 years out of date (it happens) you do not have the option to walk. You may run the risk of blackmail and she might have a boyfriend/pimp who has a sideline in burglary. Agency bookings might be the better option here.
4. Tips: Get yourself a cheap, pre-paid phone for punting and set a code to lock it. If you're in a relationship keep it in a locker or similar at work. Also if you're in a relationship, delete your browsing history. Do this now. If you go to an incall get the postcode/street before you go and plan to park a couple of streets away (or at least around the corner). Usually they will text you the house number when you arrive. Ask beforehand if there are any extras and which services are available if you want something in particular. If you want her to wear something particular (including stockings or high heels) then do it as you confirm the booking or shortly afterwards. If you don't do this the girl can legitamately claim that she didn't know that you wanted her to dress in that manner.
Avoid Romanian girls (they often decribe themselves as 'Latin') - they generally provide a poor and uninterested service (eveything "is eggstra"). If you arrive and it is a different girl - bait and switch (B&S) or the photos are out of date you have every right to walk. Do this quickly and politely: "Sorry - I've changed my mind" and don't get involved in an argument, just head down and keep going. The walking out advice also applies if there are any other circumstances with which you are not comfortable e.g. voices, particularily male ones, in the house. Of course, if you like the look of the girl it is your right to stay.
Don't just make a booking and not show because you have chickened out - this is the girls' top peeve and gives all of us a bad reputation. If you have to cancel for a legitimate reason tell her as soon as possible - most working girls will be understanding.
When you arrive for an incall you will be shown to the room, usually by the girl herself, and she will expect payment in cash before the business begins. Before you do this double check which services are available (e.g. OWO or FK), any extras, how many times you can cum and the length and timings of the booking. Politely reinforce this last point by looking at your watch or phone and even saying "So till ....then" aloud. The girl will often then disappear to stash the money - this is normal. If she starts playing with her phone during the booking or is otherwise distracted politely ask her to stop. If she doesn't respond to this ask her if she would like to stop the booking and give you a refund. Remember this your time - you have paid for her full attention.
Final tip: despite what I've written above most of the girls are decent (although there is a wide range of skills) - treat them kndly and they will generally reciprocate and treat you well.
Hope this helps and if I think of anything else I'll post some more.
Good luck!
