00:00Penis size doesn't really matter for sexual pleasure.
00:02Putting a menstrual cup inside, having a lot of sex, will not make your vagina loose.
00:07It's alright to masturbate. It's a healthy practice to masturbate.
00:24Unless you are going and licking the toilet seat
00:27or you're having sex on the toilet seat, I don't see a reason why that'll happen.
00:32STIs are sexually transmitted infections, which means they are sexual in nature,
00:39which means that you can have them through some kind of sexual contact or exchange of fluids.
00:45Having said that, it's also possible to transmit viruses like herpes through touch.
00:50But yeah, you're not gonna get chlamydia from sitting on a toilet seat.
00:56The best way to prevent against STIs is to make sure you have regular tests and using condoms.
01:11Very unlikely that you will get pregnant while having sex on your period, but it's still possible.
01:16And to explain this, I'm just going to use my uterus model very, very quickly.
01:20What happens in a period is that all of the lining on the inside,
01:24so this is called the endometrium.
01:26Think of it like the uterus is very excitedly preparing for a baby and
01:31it's collecting lots of blankets to make the house cozy on the inside.
01:35If there's no baby, the uterus gets really sad and it throws out all the blankets on the inside.
01:41This blanket is your endometrium and this is what happens in a period.
01:44Your uterus gets very, very sad at the loss of this potential baby
01:49and it throws out everything that it's built up on the inside to make it cozy.
01:55The sperm can survive inside the vagina, inside the cervix for up to seven days.
02:01So if you have irregular periods, if you are close to the end of your period and you're having sex,
02:07it's still a possibility, although very unlikely.
02:20Um, your body is not very proportionate that way.
02:23Some people can have very large hands and a small penis.
02:26There's also sort of medical syndromes where you can be extremely tall,
02:32but have a small penis. Penis size doesn't really matter for sexual pleasure.
02:42All right, so this is how it looks like on the inside.
02:45This is your uterus. This is your vagina.
02:48This is a long canal outside.
02:50And through this canal, you deliver a baby which has a head approximately 10 centimeters.
02:59So this is a very elastic organ.
03:02It is extremely elastic. It is so elastic, in fact,
03:05that if I zoom up to this, you can see that it's got all these ridges on the inside.
03:10And the reason why these ridges are there is because if you take a piece of paper
03:15and you, you know, make a fan out of it, if you fold it multiple times and you make it smaller,
03:20you'll see that it looks like a very small piece of paper if you look at it from the side.
03:25But when you expand these sides, you'll see it's actually much bigger.
03:29This is like increased surface area.
03:30The multiple ridges give it more area on the inside.
03:34It's got a lot of tissue on the inside,
03:37which means it has the capacity to expand and then also to contract.
03:42So putting a menstrual cup inside, having a lot of sex will not make your vagina loose.
03:48The only thing that can alter the size of your vagina is childbirth,
03:52and that too not in every case.
04:02All right to masturbate. It's a healthy practice to masturbate.
04:05There's even studies that sort of link masturbating more than 20 times,
04:0921 times a month reduces your risk of prostate cancer by 20%.
04:15Masturbation is really not a bad thing.
04:18In fact, it's linked to good heart health, good prostate health, like I mentioned,
04:22and good endorphins.
04:24You can even use it to sort of feel relaxed and sleep better.
04:29Masturbation, that will make you go blind.
