Bottoming not quite enjoyable

Hello fellow gays,

I recently met a really cool and attractive guy at my gym, and we hit it off. The only catch? We’re both tops.

I never bottomed before, but since he’s exactly my type, I decided to give it a shot (I didn’t want to give up on him without at least trying).

I bought a 16 cm dildo (about 6 inches, slim/thin) and played with myself. Here’s how it went:

-I did my research; I douched, mentally prepared, and was relaxed the entire time.

-The toy went in surprisingly easily—no pain at all.

-Tried a few positions, but while it didn’t hurt, it wasn’t enjoyable either. I had a semi the whole time, and it just felt like a dildo up my butt.

Logically, I get why this could be enjoyable given the male G-spot location, but I’m clearly missing something.

When I top, I notice my partners having a much better time than me - load moaning, leg shaking, color changing - the whole deal.

While I love topping, I’d like to experience that level of pleasure too.

So, any advice? Could it be the toy (slim, not much girth, and, well, not a real person)?

Is the issue that I’m not mentally attracted to the idea?

Or am I just wired to be a top?

Any advice is welcome!
