dont be inhibited or restricted by thoughts like "cheap " "loose". making love to your boyfriend is normal and fine and healthy and pleasurable. ur only loose if you Fuck other guys at the same time or u have sex with guys u hardly know or r not ur boyfriend. go ahead and enjoy sex and orgasms if both of you love each other it'll feel good. but the guy will always want more, and soon he'll be trying to Fuck you and he will, then he'll want to Fuck you every few days at hotel 81. hope he loves you and u'll be able to like it. and the guy will most probably leave you one day n you'll be miserable for months. then it will all happen again and one day u'll become more jaded n Fuck care.
and if you want sex to feel good hope ur guy aint so noob.. but then that would mean hes very experienced

fingering- is not just penetrating in and out. the guy should finger with palm up and 2nd and 3rd finger curl up in a come here motion to rub the g spot. its a kinda like a rough and spongy textured bean few cm inside the vagina on the top. this will make the girl wet n horny. and sometimes stroke the uterus all the way to the back of the vagina.
sex- unluckily, you'll probably get a less than great lover unable to have sex for hours on end without going soft after orgasms, or unable to have 5+ orgasms in few hours of sex, or he may cum and thats it after that in less than an hour. well hope he learns. learn to stop thrusting for few seconds when hes about to cum / squeeze the muscles down there to stop from ejaculating. if he has a small dick do doggy style or you lie on your side with bottom leg straight and top leg bent at the knee or over his shoulder. this 2 styles feel deeper. just initiate this if he only seems to be doing missionary the whole time. and in missionary place a pillow under your butt to flatten ur vagina n tell him to hug you n kiss you n touch ur body in other places at the same time. having sex without condoms is most dangerous in ur 2nd week after period.
on an unrelated note, the vagina is less than 10 cm long and during sex the Penis presses back against the uterus. and why wasting ur time pressing shift so much to type 1 cap 1 small
