Can we have sex when my girlfriend has her period?

Yes, you can have sex. Your girlfriend may like to take a shower beforehand and insert a fresh tampon, making sure she won’t loose any blood during kissing and petting. Some couples also have intercourse, but others find this too messy. If you want to have intercourse your girlfriend takes out the tampon. Because the tampon makes the vagina dry she should use some saliva or water-based lube to make the vagina slippery. Otherwise penetration will be difficult and intercourse painful. After you are both satisfied she collects the flow of blood with some toilet paper you have put near at hand. Realise that not all girls like intercourse when they have their period. The cervix is very sensitive in this period, making it painful when the penis touches it.
