Recently I started getting approached by women on Instagram who quickly ask to transfer the conversation to Snapchat, Skype, or Google Hangouts.  Snapchat conversations have quickly evolved into blunt propositions test include graphic pictures.  

I was toying with a connection tomorrow when I have some alone time, but the woman I’m interested in has texted me a couple of times “desperate” for a hookup ASAP.  

Are these hookups a bad idea or a very bad idea?  More seriously, are there tips to insure these encounters don’t go south? I worry about coming home with even a hint of another woman’s scent -  I really don’t want to explain how I lost a kidney.

Never a good sign.

Don’t send money. You will never see it or her again.

Although it does sound tempting,  the "person" you are chatting with more than likely does not even live anywhere near you live. Plus eventually when or if you do come close to meeting she will just send you to a website that asks for a credit card. None of these girls are actually local to you.

They'll try to get money out of you or even threaten to blackmail you if you've sent compromising pictures of yourself to them.

Scam scam scam.

They the emotional momentum.  They get you all riled up and then something comes up and they have to change, maybe they need Lyft money because their car broke down, or anything like that.  At some point they will want something.  Could even be identity stuff so they can blackmail you.

There are lots of legit ladies here or on various sites.  You don't need to go digging it the mud.
