If you can afford it a trip or 2 to see a WL would be great for giving you a few lessons in the art of sexual intimacy. If this is the road you choose to take I would highly recommend seeing a woman who is in her late 30's or older and please, call reception, be honest and the receptionist will be able to tee up the perfect lady for you.
Now if you can't afford to see a WL there is always here, feel free to ask as many questions as you like, if you feel nervous about everyone seeing it then feel free to pm me, but we are all friendly here and really would like to help.
Lesbian amateur porn is another way to learn how women like to be pleasured, other than intercourse.
Read a couple of erotic novels (not 50 Shades, it's a crap book and not what it's all about) and maybe even the Kama Sutra.
Dating wise don't rush into sex. At least go on a few dates 1st even if the chemistry is there , unless you want a one night stand.
When the time comes, don't get drunk, but definitely have one or 2 drinks to help relax you, be honest about your inexperience (don't tell her you've seen a WL if you choose to get a couple of "lessons"). And if the chemistry is there, go with the flow, it's not all penis in vagina, it's kissing, touching, eye contact and taking your time will make it more magic. If you blow quickly, laugh it off, keep the mood fun and sensual, it will actually help you last longer for the finale.
Make her feel special, make her feel appreciated and it it will all work out just fine
