I was online dating a while back and at one point was talking to this man who while he seemed very nice was a bit over keen with the texts and i backed off.
Fast forward a year and i restarted online dating and he messaged me. We had a bit of a natter via the site and he seemed much more chilled out. So we swapped numbers again and have been having text conversations for about 3 days.
Nice normal, getting to know you type stuff.
Until last night.
Texts got a bit innuendo like, fine, it was fun and flirty. Then, bam! cock picture sent to my phone. There had been no talk to cocks. Or of pictures. Indeed he had sent no pictures at all.
He started asking for one of me, i kept saying no, i was not going to send pics of me like that to somone i hadnt met. He would say thats fine i dont have to do anything i dont want to, but two seonds later i would get another text telling me to ' come on, send a pic, i want to wank over you'
nice 
Then i got a recorded voice file in which i could clearly him him wanking talking in great detail what he wanted to do to me.
I am not impressed. In fact i feel a bit depressed about it.
WHY!!!!
( clearly im not going to meet up with him now) But i just dont get why on earth men do this?
