from wikipedia: pre-ejaculate

Popular belief states that pre-ejaculate may contain sperm that can cause pregnancy, which is a common basis of argument against the use of coitus interruptus (withdrawal) as a contraceptive method. However, some studies have found that withdrawal could be almost as effective as condoms in preventing pregnancy.[10] There have been several studies that conclude no sperm is present, and thus, pre-ejaculate is ineffectual at causing pregnancy.[1][2][3][4] It is likely, however, that pre-ejaculate that follows a recent ejaculation will contain sperm,[11] though urinating will flush the urethra of remaining spermatozoa.

The more significant finding, however, was that most pre ejaculate samples did not contain any sperm and those that did had only small clumps of a very small amount of sperm which seemed to be immobile. A larger study is needed to verify these results. If these results are confirmed, they may dispel the myth that pre ejaculate fluid contains sperm.

Does preejaculatory penile secretion originating from Cowper's gland contain sperm?

Abstract

PURPOSE: To determine if spermatozoa are present in the preejaculatory penile secretion, originating from Cowper's gland.

METHODS:

DESIGN: Prospective clinical and laboratory study.

SETTING: Andrology and Sex Counseling Unit, Department of Obstetrics and Gynecology, Academic Teaching Hospital.

PATIENTS: Five patients referred for premature ejaculation, three for excessive fluid secreted during foreplay and four normal healthy volunteers.

INTERVENTION: Glass slide smears of preejaculatory Cowper's gland secretion obtained during foreplay from at least two different occasions, and semen samples after masturbation.

MAIN OUTCOME MEASURES: Microscopic examination of air-dried smears, and routine semen analyses.

RESULTS: None of the preejaculatory samples contained sperm. All the patients had sperm in routine sperm analyses.

CONCLUSIONS: Preejaculatory fluid secreted at the tip of the urethra from Cowper's gland during sexual stimulation did not contain sperm and therefore cannot be responsible for pregnancies during coitus interruptus.

from this and my year of pulling out, so long as i don't blow a load, not urinate, then begin banging again i have nothing to worry about

and i've had nothing to worry about.

and you can't ever get std's unless you've had them all along.

thus never worry about wearing condoms.

Actually it's quite simple science.
