No. I recently had a 19 year gap with a woman I was seeing. There were issues though. Wherever we went people thought she was my daughter. I didn't like that, but some guys do.
The age gap presented some big issues in conversation too. We related to nothing. We were working off pure chemistry, which only takes you so far. I guess if the chemistry was stronger, it would have been easier to get over. Personally, I would not do it again.. but you never know, could meet a better match with the same gap and have it work..
A lot of people will tell you that it is wrong or bad or something like that. The thing is only a problem when your interests are very different, and then when he ages to the point that he no longer is the same person. If you become a couple, then when you are 50 and still wanting lots of sex, he will be 67 and definitely slowed down. Possible the ED mentioned on here. And not too long after that you will find yourself caring for somebody who cannot take care of themself. As long as you look at all that, then whatever you decide works for you is your business, not everyone else's.
Many women are attracted to older guys. Not for any weird reasons but, because the guy is secure with himself, capable and independent and that is attractive. Just like how younger guys that have all that are attractive too.
I'm 44 and I go out with who I am attracted to and who is attracted to me. Most people think I'm about 35. The age difference is an issue when there is too much of a maturity gap. Also, many women see men their own age age as immature.
I've heard the general rule youngest female should be is 1/2 guys age plus 6 but, whatever, if you meet someone you really like you should go after them.
