TMI Warning! With these semen ysis results, how often should we bd to give us the best chance?

My husband had an appointment for a semen ysis on Wednesday February 10. But we had a big snow and had to reschedule it for Friday February 12. So when it came time for the appt we hadn't had in around a week(you are suppose to have d 2-5 days before the test) and it had been 7. So about 5 hours before the test we bd'ed. My husband went ahead and did his thing when it came time for the test. We were worried that the results wouldn't be good because of him just 5 hours earlier. But when we later got the results we were told that everything looked great, the count, motility, everything. So the reason I'm asking this is I am wondering would it be better (and give us a better chance of conceiving) for us to BD every day & maybe every 12 hours after a positive OPK? Since his ysis was okay so soon after am I right to believe that daily probably wouldn't have an effect on depleting the quality, and quanity of his um... baby batter?LOL I am on day 11 of a 26 day cycle, usually getting a positive CBE digital OPK late on day 13 or early on day 14. I am also taking robitussin, baby asprin, a prenatal vitamin, and a b12 and b6 vitamin. Are these things really helpful in conceiving? Any help will be appreciated! We've been ttc around a year, but I haven't been on BC since DS was 6 months old. He will be 7 in may. But I've just discovered all the TTC forums in the past couple months. Thanks!! :)
