Men and buses

Right after months of being single and desperately seeking company, why is it that there is now an influx of eligible, and very available men knocking on my door? '
What on earth are you complaining about?' I hear you ask. Well here's my problem, I am incapable of going out with more than one person at a time, as even though they may be just dates and hardly a bloody commitment I still feel like it's wrong and I'm somehow being dishonest by doing so. This I believe may be to do with being married for the last 10years and being completely faithful to my husband or it may be that it was drilled in to me by my mother after my Dad left home that it was very wrong to be with 2 people at once.
So what do I do?
I met a really nice guy on Saturday night, have a great laugh with him, we swap numbers and have spoken and are hopefully going out next week(I've given up believing plans so always pre-empt them with 'hopefully')
Then hey presto someone who I'd given up on then contacts me on Monday and several rather naughty texts ensued, but I have no idea where that may lead as he seems to be a bit of an enigma.
So do I write off the guy who I met at the weekend even though we may actually hit it off (and he made me laugh a lot) or do I agree to see other guy who I have an unbelievable physical attraction to but haven't got to know him well enough yet to know if we match in any other way!
And I won't even go into the story about the 23year old PE teacher (he did have gorgeous eyes though)
This coupled with the fact I'm an indecisive Libran who constantly weighs up pro's and con's, and then has an argument with herself over which ones are pro's and which ones are cons, doesn't make for an easy nights sleep! Oh why can't things be simple. Times like this where I wish the American way of dating several people at once was considered the norm here.
