You don't really know to be honest, after you have sex if your boyfriend is eager to have sex with you that means he's satisfied. However i'll just sum up some things because I'm not sure what you mean by just 'sexually'
If you are having sex then I really suggest you moan really hard and make out while he's doing it with you. I also suggest trying out new things like sex in the shower, it's lots of fun.
If you are giving oral which is personally one of my favourite things to do with my boyfriend, try something new like have him sit on the couch and you on your knees, if you have eye contact when giving a blowjob, the male gets really horny and attracted. Try deep throating, it's one of the best techniques and males love it. Handjobs are great but I personally prefer giving a blowjob.
I don't have much experience with anal but I suggest trying out new positions for this type.
just show up
If they are lesbians yes.
Make love to her gently and ask her what she likes.
Dont know, your not sexually attracted to him?
You cannot be a lesbian if you seriously have a boyfriend - who you are sexually attracted to, you might be bisexual -if you are sexually attracted to girls too and not just curious. Of course you don't wanna kiss anyone besides your boyfriend, if you had a girlfriend it would be the same thing, you kiss the one you love. But since you don't know, then i think you are not.
Feed her during sex.
Gently put your thumb up her butt
Maya Angelou's mother's boyfriend's name was Mr. Freeman. He sexually assaulted Maya when she was a child, an experience she detailed in her autobiography, "I Know Why the Caged Bird Sings."
Find a boyfriend, or a girlfriend, and take it from there.
eat her out, lick her vagina, stick your tongue deep into her and wiggle it around
Since the female is a masochist, the male will bite her to satisfy her sexually.
I don't know your girlfriend, so I can't ask her. But you can, and you should. Talking about sex is not only fun, it's healthy. And it can help both of you to enjoy your time together more!
