are there any suggestions for suitable strap ones for locked guys? Some strap on harnesses are designed for women and don't fit right. Others look to fit but are hollow so your penis can fit I side. That won't work either.
This one is comfortable and will accept most dildos. Picture of it on in my 'Kitten's Property' album. https://www.ebay.com/itm/Genuine-Sp...ness-Purple-/162731239842?hash=item25e389a9a2

Locked in Lust has a strap-on harness designed for guys who're in chastity. https://lockedinlust.com/product/crotch-rocket/
