Hi, I've been having sex with this girl for a while now and I already know that I have a tendency to push against her cervix (which she says she has gotten used to feeling) but recently we tried doggy-style. While in doggy, she tend stop ask for it fast and deep but afterwards she starts to feel nauseous and once she almost vomited afterwards. We've decided to take a break from doggy until we figure out a way to stop her from feeling that way afterwards. Anyone care to offer some advice as to what we can do so she feels good after sex? Another question, I love to go down on my girl and she likes to give me oral as well, but two things tend to happen during our oral sessions. One, my tongue tends to hurt for a few days afterwards and therefore I can't go down on her. Two, she's scared about me ejaculating in her mouth and the taste of it so she never gets me to ejaculate from oral while I tend to give me multiple orgasms and sometimes she will squirt. So, overall is there anyway I can increase the strength of my tongue so that little strip of muscle under it doesn't hurt for days and is there anyway I can convince my girl to not be afraid of my ejaculating in her mouth so she can at least try is once before she makes a decision about it? One last thing, I've always wanted to try breast sex at least once and my girlfriend has a pretty large pair. But I can't seem to convince her to let me try it once cause she just says that she doesn't want me between her breasts. Anyway I can persuade her to let me try it once? Thanks to anyone who answers.
