Strap-ons for men?

It seems like a odd question but why are strap-ons on the sex toys for men section

Hollow strap ons are designed for penis owners to use on their partners (of any gender) with the penis going inside the dildo. People use it for different reasons, sometimes it’s to give the receiving partner the feel of a different size penis, some people use it when the wearer has difficulty getting or maintaining an erection or ejaculates too quickly. Sometimes it’s a humiliation or punishment thing. And there are probably other reasons too

We have a few different 'strap-on' dildos which we use with harness briefs.

We normally use selected ones for her to peg me.

Sometimes though she likes to work on me with her hands or wand attachments to make me come alone.

Once I've calmed down I can then use one of the strap-ons on her to allow her to come too.

They are different sizes and shapes too so she gets a different experience to normal sex with me.

Can it be used for male solo play or no
