I agree with WinterDreams that you should find opportunity to safely meet men with similar interest either through course, as suggested, or by joining local clubs. I would recommend not trying the bar scene as that usually doesn't satisfy the need to find someone. Also, join you local gym - not only can you work on keeping a good figure and staying healthy, but you may just find a fellow there.
Many of my friends have found their guys when they weren't even looking, but were instead just enjoying life and ended up finding a guy that enjoyed it with them.
Hope this helps,
