Stopping Uti's

Jessica
Hello ladies,
As I am sure many of you have had the dreaded Uti. 
I was just wondering what your remedies are? I constantly get them straight after sex and have to take a single antibiotic. Which I don't want to take every single time I get busy with my soon to be husband and once I start tying for children what will I do then? 
Thanks for your help guys! :)
