My Man and I Have Been in an Open Relationship for 5 Years and I'm Having Fun

My man and i have been in an open relationship for five years. The problem is that i no longer want to fuck my man. I encourage him to seek out others again, but he's too lazy to go out and meet people. So now i'm feeling this growing pressure to meet his sexual needs - even though he has the option to go elsewhere. What would jo do in this situation? Please help.
