What Happens After a Vasectomy?

I want my husband to get a vasectomy we have completed our family and After many health issues I don't want to get my tubes tied. I have talked to him about getting a vasectomy but he is "afraid" to. I think it's the fact we don't know how it is after.?. And would rather hear from an actual person that had it done rather an a doctors' explanation 
Anyone please
