AMAZING!
I did not even know a vegetarian dating site/vegan dating site woudl exist butthrough Pinterest I somehow tripped over Vegetarian-Single.com. Before I was frustrated. All teh men invited me to steak rerstaurants for first dates :D And some did not even know the difference between vegetraian and vegan (I am vegan) and proposed to invite me to a bar to have cheese and wine instead: D
Luckily, I found Vegetarian-Single.com but it took me hell a lot of time to find Mr. Right. So my first advise: Stay in there. Like in real world, you need to search.
I invested some bucks in a gold membership and kept searching for guys in my area. Secodn advise: go for a three month or six month gold membership. Like in real life again, you won't find anyone in three weeks.
But everything was worth it, found a nice guy and we dated for almost half a year and had soem nice relationship. Life again: it is over! But the expereinces were great.
