Condoms

Is it true, a man will ejaculate more using a condom if their sperm count is low? Ladies, have you heard of the reversal? meaning you use a condom he ejaculate, take off condom and insert his sperm in you? I'm feeling some type of way about this, because in 6 years we have used a condom twice and that's when we first started dating. And now all of sudden he wants to try this method, because he feels we can get pregnant. HELP ME UNDERSTAND IF I'M OVER THINKING THIS SITUATION? Right now I'm feeling some type of way about it and I can't hide it....
