Film: A Complete History of My Sexual Failures

I watched this film today, which was a documentary following a slacker-type guy called Chris (who had an echo of Kurt Cobain about him), who had been dumped by every girlfriend he'd had and could no longer get it up.
The film came to rather a big snag early on when none of his ex girlfriends wanted to be on film. He eventually persuaded a couple of them who he went out with quite young. Both of them were quite smug and looked years older than him, even if they did have big, bland houses. I think he had a lucky escape with those ones. Unfortunately later on he met up with some of his exes who he had clearly done serious wrong by, and they were interesting, attractive and independent.
I thought the film was slow and relentlessly depressing for some time. Chris was a pretty unlikeable character, in my opinion, I didn't feel he had much charm, he just stumbled from one crisis to the next. I don't mind a scruffy bloke, but having to get his mum in to clean pubes from round his toilet was a step too far. Not appealing.
He didn't seem to have a lot of answers as to WHY he was such a dick. Why didn't he reply to Olivia's love letters? Why did he propose to one girlfriend and then never set a date for the wedding? That particular girlfriend still lived in the flat they'd shared and it was probably the most interesting part of the film as they cried together. How silly of him to declare himself still in love with her, when she was pregnant. It was textbook teenager behaviour, and just emphasised how emotionally immature he was.
The film lost it in the middle; first with his trip to the dungeon (how would getting his arse smacked and his dick twisted help him get a hard on?) and then when he decided to deal with his erectile dysfunction by doing a whole packet of Viagra. I thought it was pretty insane. Can't you have a heart attack like that? When he ran out of the streets begging people to fuck him I thought that was tantamount to sexual assault; I would have punched him in the face had he approached me like that. He lost all of my sympathy at that point.
Yet incredibly, he met his next girlfriend this way! And she was really good-looking and had a good job as a journalist. I was glad the film cheered up a bit, but it seemed a little too neat.
All in all Chris reminded me of the kind of person you know who just won't grow up, and who blames other people for all their problems. I think the film was meant to be funny, but I didn't laugh very much. It just made me realise how stupid men can be in relationships. And how much women have to put up with. (insert sexism complaint here!)
