It's 3 weeks today since I first met him and I've seen him 4 times in that 3 week. I started talking to him 4 weeks ago tomorrow when he took my number from my car after seeing me. For the first 3 weeks we flirted via text and the odd phonecall and he was always asking me to send photos. My response was always no I don't do photos of myself, I need to know someone before I do that and no I can trust them. Anyway the end of last week he said I might not be able to text tomorrow because I've ran out of free texts and although I've text him he has not replied but he has rang me Sunday, Tuesday,Wednesday,Friday, and we were together yesterday. So in a week I only had no contact 3 days. We had a good time yesterday but when he left I felt a bit confused because it's the only time he has left me without sending a text of kisses as soon as he has left. And We never discussed meeting again although he knows I'm at his neighbours on Monday. I really want to see him again should I call today or wait and see if I see him tomorrow but I forgot to ask what time he was working. I miss him when we aren't together but don't know how he feels because in the first few weeks while we were textin he was all miss you and your sexy smile but while he isn't textin I'm getting none of that. I'm so tempted to send a pic out of the blue like he always used to ask for but will I pic of me in sexy undies have any effect on I guy I had sex with so he has seen me naked. (Yesterday wasn't the first time so I'm hopeing its not a case of he's had what he wanted) advice please.

You are sounding really desperate. Let him call you.
If you have already had sex with him what is the deal about sending him a picture, unless he is asking you to send him pictures of you half naked and in your undies, in which case I'd say, don't be stupid!
