Unless you're married to someone who won't indulge you and this is the only real problem in an otherwise happyish marriage in which you'd like to stay, parties aren't a good idea. I've never been to one, but of course have had a look at the various sites online. Expensive admission, and relatively costly sessions timed by the minute with 'models' who'd not associate with you otherwise.
Yes, talking to girls is difficult, yes, the rejection rate is about 90%, yes, looking for companionship on whatever level is a miserable and frustrating pursuit that rarely works out. But this is every man's lot, except for sports, movie and rock stars. Those of us not so fortunate have to develop our conversational skills and remember that while we men are seduced through our eyes, it is very much to the advantage of the physically unattractive man that women can be seduced through their ears.
I'm old now and have been married three times- life has taught me a bit about the species. Somehow- and unfortunately there's no magic way of doing this but it CAN be done- learn to talk to them. Ask open-ended questions about their feelings and nod sympathetically without offering any solutions.
But believe me when I say that finding one girl who indulges you (and may even like it!) out of friendship or love is worth more than ten 'Stipendiary Venuses' who are only there for the money, and secretly hate you.
Start innocuous conversations with five attractive girls a day, and I can pretty much guarantee that within two weeks you'll have some awfully humiliating memories, and one or two new friends.
