Get some Astroglide lube...it inhibits the motility of sperm giving you more of a chance that you won't knock her up.

Can I use Astroglide while trying to conceive?
Astroglide is not a spermicide and will not kill sperm. Studies have shown, however, that Astroglide as well as other topical lubricants do inhibit the motility or movement of sperm. Knowing this, if you choose to use Astroglide, we suggest using a small amount applied to the outer area. Discontinue use if conception is not achieved in a reasonable amount of time. It is always advised to consult your physician first and to follow his or her recommendation.

RESULTS: Commercial lubricants inhibited sperm motility by 60-100% after 60 minutes of incubation. Sperm exposed to Replens or Astroglide were nonmotile and nonviable after incubation for 60 minutes, similar to the control, nonoxynol-9 containing product Gynol II. Canola oil had no detrimental effects and was indistinguishable from Ham's F-10 in terms of sperm viability and motility. CONCLUSIONS: For couples with infertility, the use of vaginal lubricants during intercourse is not recommended. In cases where a lubricant is required, careful selection can maximize sperm motility and viability.

I also recommend the Nuva Ring vaginal ring rather than the pill.

with the nuva ring and astroglide combination...I feel confident to "blast" in my girl all the time.
