It finally happend. I talked about it with my partner and she used a dildo on me the other night and IT WAS AMAZING. she loved every second of it and I Loved every second of it. I knew I'd be hooked but good golly do I want to get pegged more. That's it. That's the celebration On to the question

Harnesses. Are their harnesses sized? Or are they one size fits most? My girlfriend is a bigger woman, I'm not sure on her size, but I want to get a harness so she can peg me propper, ideally I'd like to surprise her, if I need to get one sized I wouldn't mind blowing the surprise by taking her shopping for one instead. Any help/suggestions would be amazing. Thank you :)
