Most people need and want sex, irrespective of their age, race, looks, net worth, etc. . I guess, we would all agree on that one.
IMHE, most guys cruising for sex are either into their peers or into younger dudes. Most, but not all.
I happen to be interested into guys significantly younger than myself. My friends call it 'the mid-20s syndrome'. So far, I have been reasonably successful.
Few of my own rules
Always respect a 'No'. No matter how good-looking, in-shape, self-confident, etc., you might be, nothing is worse than begging around for sex. I never hesitate to try, if I am interested, but if the guy signals a 'no' of any kind, I'd quickly move on to give him his space and avoid wasting my own time.
Most guys try to land the hottest dude around (usually 'the hottest' as defined by the mainstream porno industry standards), many men around have their own preferences and would even find a much older, out-of-shape, beer-bellied, etc. guy, to be the man of their choice. If you keep your eyes open, you may notice that this happens more often than you would expect it to.
Most guys I have met, have their own preferences when it comes to the age group they are interested in. At times, and depending on the circumstances at hand, a few guys show a greater degree of flexibility than the other dudes. I would never waste my time with guys who have set their rules in stone, and I do not happen to fit in.
As a rule, big numbers always win. If you wish to stick with your preferences, chances are that the old adage 'the more the merrier' applies here. It isn't too bad to have the laws of statistics on your side.
If you happen to be an 'older' guy looking for the younger dudes, keep in mind that some of the young 'hotties' would love to mess around with you, if they can do it in private. I have met a few hot college dudes who would not want their gay peers to know that they are into 'older guys'. They hate to be labelled 'freaks' or whatever. I could not care less. I am equally happy to do the deed in 'public' and/or in the privacy of my bedroom. I would not call such guys exactly a 'relationship material' but they frequently make the best f-buddies.
Eventually, every age group just like every individual has its own 'pros' and 'cons'. Most cruisers are obviously very skilled at stressing the 'pros' while trying to hide the 'cons'. If you feel that say, your 'net worth' might be one of your 'pros', no harm in putting that on display within reason. If you happen to be a 'gym rat' with a 'killer body' and see that as your forte, show some skin... There is nothing wrong with making do with what you have got.
