Ok so you want to host a game.
Couple of options.
1/ although it's a dynamic IP your IP doesn;t actually change that much. So if you find out your external IP to the world ( usually in your router or modem info) you can host a game.
SO people say that certain ISP's change the dynamic IP when they monitor regular up and down stream activity ( a game or torrent file) No idea if this is true
2/ You can install a piece of software that notifies an external forwading site what you IP is at all times and redirects traffic to you. No-IP or DYN DNS or similar.
You would have to make sure incoming ports were open and indeed go to the correct PC ( if you have more than one computer sharing your home network)
3/ Some modem routers ( Netgear that i know for sure ) have a setting that does the updating to DYN DNS for you ( so you dont need a piece of software installed and running on your PC). You make an account with DYN DNS. Put the account details in the modem router and it constantly updates the DYN DNS service for you.
Very useful for remote desk top VNC systems and similar.
For example

points to a "how to" i made for the RC helicopter guys last year. No matter what my IP is my router unpdates the dyndns service ( free) so anybody clicking that link always connects to an old linux PC i have hosting web stuff
Most games i know of use a lobby system. If you intend to try a SADS system then you might just be able to get it to work via one of the many dynamic DNS services out there but you'd need to do some game specific research first.
Good luck
