Sperm analysis

Hey were just waiting on hubby to get some time to do a sperm analysis but I was wondering I think he’s pretty nervous about it incase there may be an issue there but I also think he doesn’t like the idea of masturbating into a cup, he’s very personal and I’d say a bit of a prude. so I was wondering to help him out is he able to have sex with me then pull out and finish in the cup or will that contaminate anything?
