you are the only one who can answer the question as to whether or not you are ready for casual sex or not...
Feeling used? Honestly, only you can make you feel that way... If it's a mutually pleasurable experience... no one is getting used... You really have to find out for yourself what your expectations are out of this guy... and for yourself...
As for his age? it's a year -- so what... are you looking to get married? do you want a lifelong commitment wiht him? There's a lot to be said for someone making you laugh and in my book - that's a key feature.. because it's either there - or it's not... and if it's not there... well he better be rich or hung like a stallion... because when all is said and done - what's the point of... anything... without laughter.
I went thru my 20s, not so much doing the casual sex thing, but even with two engagements (very long story) I never saw myself as a getting attached emotionally, I wasnt the hold me... love me... send me flowers on my birthday type, bring me soup when i'm sick type... I never felt he had to spend the night because it's what he thoguht he wanted or was the 'cost of doing business' because other women wanted it.
Sex was great but it was just that - it was sex... relationships were mutually exclusive... I had really good friendships that I got the warm fuzzies from.
Now that my 20s are way in the distance.. I'm not so sure i feel that way anymore. I wouldn't change anything i've done... except maybe not let myself get so old...
It's your life... you know what's right for you... and more importantly you know what you need...
Good luck and if you are going to have sex this weekend - be responsible - protect yourself
