Sharp Pain When Inserting

I have noticed this problem for some time now, but I’m not really sure when it started. When I insert the tip of my dildo, only sometimes, it feels as it has a razor blade it seems so sharp. It’s painful, no matter how much lube, foreplay, or different positions. Other times, I don’t have that problem-same (clean) toy. I’ve never had a problem with fingers or the real thing. I think this started about a year ago, but I just let my body take a rest and then next time it’s fine or I just fully insert the toy and the pain disappears. The problem is only with the first inch-two inches? Was just wondering if this is the same problem for anyone else or if anyone has some advice.

Thank you in advance🥰
