Backdoor sex?

French guy admited to me that he's had threesomes. We text each other all the time...mostly talking dirty via SMS. Funny thing is we've never done it. He goes on and on about how he wants me to "suck him dry" and keeps begging me to have him stick it in my ass. I may be a prude, but come on is he serious? How about I buy a dildo and stick it up his ass?! I mean, I'm open to a lot of things, things I haven't experienced. There are two things I just can't get myself to do. 1) Have some guy back door me and 2) Have sex with another girl, regardless of threesome fantasies. I realized I'm not going to go far with this guy and that I should use his sexual experience to give me some experience. I want him to teach me how to do it and do it right. We were getting hot and heavy on wednesday and while he's sucking on my tits and petting me heavily, his hand begins to wander towards my anus. That's when I pulled the breaks and told him I wasn't comfy with that Idea. I guess this put him off and he just wanted to go to sleep. This is what's going to happen. I'm not going to text him or talk to him as much....maybe only see him once this week if that. He acts like he doesn't need someone, yet all he ever wants to do is cuddle. Funny thing is, I don't understand why he's still around. I mean, it's not like we've ever done anything. He's gotten to second base at most, never any penetration. I'm available, but not emotionally available. He text me "are you mad?" today, because I refused to see him yesterday. It's all fun and games now. In the meantime, I went on another date with Polish guy #2 on sunday. Don't know why I got all dolled up, I wasn't even attracted to him to begin with. He works for the same company, just a different department. He's nice, he tried to hold my hand while we were walking around the streets of new york after we ate at some cute little french restaurant. One thing's for sure. I think the french infatuation is fading. Thank God.
