Hi
This is divar from Bangalore. My gal frnd's menses date stared on August 5th and ended on August 8th... we had sex without protection on August 15th with the feeling that can do without condom.. can you please answer me was that safe period to do?
Please reply

No, there is never a safe time to have unprotected sex unless you are actually trying to conceive.

Depending on her ovulation schedule, this appears to possibly be the BEST time for her to get pregnant.

Sir,
But I didn't enter my penis fully into her Virginia.. she s still a virgin now... just entered in the opening of her vagina only...
If periods was on August 5th.. then up to 14-16 days safe to have sex na?

It's a VAGiNA, not a virginia. It doesn't matter whether you entered a just the opening or the entire way, she is no longer a virgin, and she could still have gotten pregnant.

There is no safe period, she can depending on other factors get pregnant any time of the month, even during her cycle.

Next sorry to burst everyone's bubble, but if you entered just a little bit, she is no longer a virgin by the meaning of the word.
