Female orgasm necessary during TTC journey

Beautii

Is it true that it’s better to orgasm before inserting semen?? My partner and I are using a donor and we just insert it right after he passes it to us....not during sex...I just lay with my legs up for 45mins-hr....if anyone has any ttc tips on helping please Share....this is our second month trying...I’m 37 and I’m ready for a baby girl...but at this point I’ll take whatever I can get!!!
