The 5 steps to SA success without really trying
1 - send your intro letter. A brief description of you and what you are looking for. Then end it with a question regarding their interest level so far.
2 - if they express an interest, start to qualify them as to your allowance $ amount. Ask them if (whatever amount / range) seems reasonable.
3 - if they say they are still interested, let them know you think they are attractive, and more specifically the type of arrangement you are looking for and the exact amount you are willing to spend per date.
4 - if they are still interested, ask them to txt or email you for the details of what this first date will be like.
5 - when they txt or email, let them know that a simple M&G will only allow you to pay for the out of pocket expense (food, drink, etc). But if they agree to a paid date that would require a certain level of physical intimacy. And best if you describe that in detail. I always ask for little knowing that more will happen 50% of more of the time. Sometimes a whole lot more.
The advantages for asking for some light physical intimacy are semi-obvious. You can offer a lower $ amount in general while possibly getting a higher level of intimacy than requested. This dynamic my change if the girl decides she is ready to go all in, and she may try to upsell you. And then at that point (if it occurs) you will have to make your final decision as to what you are ultimately willing to spend.
Me? I pay my $ a date period the end, take it or leave it. And I still have more girls than time to fuck them.
