Hey all:) Haven't lurked this forum in a while as I haven't really had any big issues getting girls, or been interested in the art of seduction lately.

I have some questions now though. Lately I have been having problems getting really turned on by woman. Sometimes I'm shocked how little it affect me having a naked body beside me and needless to say.. it's terrible.. when both I and the girl I'm with really wants to have sex and I get stressed out, over think the situation etc, it can result in having a hard time getting it up. I have never had this problem. It started about a month or two ago when I failed to lay a 9 because of this shit. I had been drinking some and it was outside and kind of cold, but still, I had never had that issue before.. and I believe that this memory plays a part in why this problem reoccur. If so, how can I do something with it? I also have been having quite a lot of sex recently with different girls, can this have something to do with this? Let's say you had sex the previous night with some girl, then the very next day are headed for bed with another girl, can that be a cause for this issue? Do a couple of beers consumed play a large factor? It hadn't been a problem before.. perhaps it's a combination of all? Seems weird if my sexual desire would decrease seeing I'm only 22. I want this bad trend to change..

Second question
I had a one night stand this saturday with a girl that actually was interesting to talk to and seemed like a really cool person. We met at a pub and talked for 2-3 hours, and as I usually do, I kiss closed and brought her home. We talked for a bit and I knew she wanted to have sex. Eventually, after a terrible stressful time, some talking, fooling around, I finally managed to get it up somehow (to some extent lol), but that's not the point... because despite that, all around, I actually had a really great time with her for the 7-8 hour period when she was at my place and we seemed to get along really well. I usually don't give a damn about the girls I have sex with, but she seemed really cool. As dumb as I was I didn't exchange numbers with her, but she lives nearby and I'll most likely see her again at the local pub in the near future. The question is wether I should try to befriend her on facebook so I can exchange numbers, or try to get her cell through some other people that might have her number, or if I should just try to reestablish contact the next time I meet her? And if I shouldn't try to contact her through facebook or cell, how should I proceed the next time I see her? I don't want to come of as a needy fool, I just want to hang and see what she's all about and have some more (hopefully more successful) intimacy with her.
I know she could be regretting this whole thing as it is a common scenario I'm familiar with, but this time I don't think this is the case for a variety of reasons. She really hadn't consumed that much alcohol, and we really had a great time. I can't tell wether she's like this with everyone, but she specifically complimented how easy I was to talk with, and gave some strong ioi's as she was on her way home. The whole night was really more comfort building than sex in a lot of ways.
She could just look at this though, as I usually do, as a one night stand and that's it.. but if that's the case I can hopefully do something to change that.
I don't know wether I actually want a relationship with her, only that I want to spend more time with her.
