Heeyyy, I'm 21 and I feel like most of my friends have the same issue. on the other hand I can just reach down there for two seconds and my eyes are rolling back. I ask them if they play with themselves and they say it's not their thing either. For me I've been doing it since I was 14. Not that I was touched wrong young or anything that's just when I got interested. So that being said it's really really important to know yourself. To know what turns you on. At the same time you shouldn't feel awkward about watching porn. Lately pornhub has some intense stuff. Maybe start with some light amateur porn. Also if u don't want to stick your hands down there Get someone you trust or if you have the balls to do it yourself- they sell tiny vibrator rings at shoppers in the lube section. Buy one of those and just hold it on your clit and your eyes will be rolling in no time. Just relax. You have to know what it feels like to cum before you can cum for your man
Hopefully this helps and sorry if it's graphic
A woman can orgasm and some woman can ejaculate (squirt) but a woman can't cum, the white creamy fluid that comes out the vagina during masturbation or intercourse is just vaginal lubricant and cervical mucus combined to make it look like cum.
That tingle you feel could be your orgasm because they come in every size and form there is, don't go by what you see in porn with all the screaming and thrashing about because that is most certainly fake. A female orgasm can range from just a mild warming sensation to totally mind blowing depending on the person and how relaxed you are at the time, not every woman can achieve orgasm during Intercourse alone without some other form of stimulation too but don't feel bad about it because your not alone.
