First time toy user.

I have a question that might seems obvious but I'm not sure because I've never used a toy that you insert. I have a vibrating wand. I just got a toy with a clit sucking part and a dildo on the other end. The dildo is long, maybe 9 inches but not thick. I haven't had sex in almost 3 years due to my husband battling problems with his testosterone. So, I used the dildo part last night and everything went good. But I felt as if I was almost too tight. Like it didn't smoothly go in and out. And I did use lube. Anyone ever experienced anything like that?
