Are some people just naturally tighter/looser than others down there?

[Teox]

Sorry if this sounds like a stupid question but I generally like to know.

I'm a top and I've never been bottom, I'm happy being a total top but I would like to try being bottom even just the once.

I'm just too tight, I can't even hardly get a finger inside me with lube and poppers.

I realy want to experience being bottom, it's like I'm missing out in life as a gay guy.

I've tried lots of things, relax, plenty of lube, poppers, got myself a butt plug.

I wish there is a tablet I can take so I can experience being a bottom.

Are some people just naturally tighter/looser than others down there and any other advice for me?
