I’m a straight, 34 year old male and would date any woman between the age’s of 24 to 45.
(I know, I cast a wide net)
I am 51. I would date anyone from 30 to 70. It depends on the person really though.
Male 46. My dating profile is 35-55 but in reality I rarely respond to anyone under 40.
I’m a male 54… my wife gets really mad if I date anyone else.
I am an almost 42 year male. I always thought that I liked older women when I was a teenager because the ones that appealed to me most were always 25 - 33. Then I moved into that age range myself and all was good. Now that I am well past it, I am starting to realize that this might be a long-term problem. My preferred age range is still 25 - 33 and it isn’t relative to my own age at all. I hate to say it but I find the vast majority of women my age or older to be about as appealing as a guy (not at all for me). The really young ones don’t do anything for me either.
I’m 31.
If - god forbid - my relationship ended, I’d be looking at women aged 18-25.
Male, straight, pushing 60. Is she over 18 and has a pulse?
I’m 61 and quite happily married. But if I was to find myself in the dating world, I’d probably stay within 5-6 years of my age. And at this stage of life, I wouldn’t want to be involved with any man with significant health issues, i.e. someone looking for a nurse. I’d want a partner, not a patient.
Altho, in reality, should something happen to my husband, I doubt I’d be out there looking anyway. I’m too old to train another one. 
I am 43 so I can date anyone in between the ages of 21.5 and 72! Whenever I am on a date with a young woman and things aren’t going well, I usually ask if her grandmother is available.
Gay male, 69. I’ve never had any age preference whatsoever, and am happily partnered to someone 20 years my junior. The age difference adds an interesting dimension to our relationship, but no particular problems. Age is only a number.
Male 52. Separated and possibly thinking about dating again at some point, although I’m not looking forward to it.
40 would be too young, I think. 60 would be too old, I think. Ideally 45 to 55 would work for me.
I’m 33, female, and dating a 30 year old. I wouldn’t date someone younger than me again, though, I’m surprised by how much it bothers me to be the older one.
What are you doing next weekend? 
I’m 49. Realistically, I’d probably date someone within ten years either side; so 39-59. Rules aren’t carved in stone, though; if someone outside that range was ideal in every other way, and interested in me, why not?
I’m a 42 year old straight guy. I’m happily married. If (shudder) I were looking to date again, I’d probably be looking for someone within about 5 years of my age, so 37ish-47ish.
I’m 46 and married, but if I were to start dating, I’m thinking maybe 35-55 or so, but probably concentrated closer to my own age.
Mid 40’s and I don’t really have an age range. Below about 25 their brains aren’t done physically maturing so that’s a line I try to stay above. Other than that I don’t really screen by age.
47 and married. If I were dating again, I’d probably put the lower limit in the mid-30’s, no upper limit. I think of one’s 20’s to mid-30’s as the time to do fun, stupid things on the way to figuring out who you are. I’m too old to be good for that.
I’m 34. 18-25 would be my preference for anything long term and exclusive, but I’d happily date someone my age or older if it was a short term or an open relationship.
67, primarily 55 to 67, but seldom below 45
