General advice for a guy?

Hi, Really generic post i suppose. I am based in UK as I am sure that’s relevant. Me and my partner have opened up our relationship as it was a mutual desire and we do both enjoy it. It does not affect our relationship negatively!

The only thing I am noticing is I find it really hard to find anyone to develop any kind of casual relationship/ FWB situation. Same goes for ONS but i am not that into that.

Whilst this is a given it still sucks and doesn’t make me feel great! She obviously doesn’t have this issue, though this doesn’t bother me!

Is there anything I can try? I am using apps but not really any luck. Advice is welcome.

Again I recognise this is like the most common thing and maybe nothing i can do about it, but it doesn’t hurt to get advice!

Thanks!
