Swollen Vagina for six days after first orgasm (fingering), swollen breasts, blackouts?

I went off my anti-psychotics almost six weeks ago (which are supposed to affect sex drive), and within the last few months I've lost about fifteen pounds, and have become much more...sexual mentally and physically. I've become very sensitive all over my body, and I had my first orgasm on friday (it is thursday night right now), and my boyfriend noticed that it was slightly more...cushiony in there, and since then I have become really really swollen, and earlier today it hurt when he inserted just one finger, it was so tight, but it was fine after a few seconds, and I could feel everything...I've never been able to really feel things there...but anyways, my breasts have at least doubled in size (so much that I haven't worn my bra for the last few days because it is too small and uncomfortable) and I don't really have the money at the moment to buy a new one...I could ask my mum, but she's tight on money, and my boyfriend has offered, but my breasts increased noticeably in size in just two days! What if they keep growing? Ack! This is starting to scare me, especially the swollen vagina...what should I do? I may talk to my therapist tomorrow, but Idk how to tell my mother...It's an awkward subject...and I know she doesn't like me being sexual with my boyfriend...Is it possible he could have gotten me pregnant from sperm that could have been on his fingers? He said he's sure he washed his hands, but he almost never uses soap.../: I don't really think I'm pregnant though, because I am not hungry or craving anything unusual (I crave salads quite often, and those wild buffalo hotwing things, but that's normal for me)...I have never been this sensitive or swollen, on my breasts or inside of me...

Also, I'm not sure if this really goes here...but...I was wondering if anyone else who was sexually abused gets really nervous during sexual encounters? Like...I get so sometimes I have to bite my lips or something to keep from crying...and I don't know why...And yet I want to be touched...and also, sometimes I get really scared, and I black out...this used to happen to me a lot before I took my meds, where other personalities within me would take over, but things got really scary...(I ended up stabbing a girl in the leg with a pen at school, and that got me sent to the mental hospital), that was when I was fifteen...I am seventeen now...and the blacking out thing, it happened a lot when I had sex (I know, I shouldn't have had sex, and I haven't had sex for over a year), and I feel really bad, because my boyfriend (who was my first boyfriend, and the only one I've every really done anything with other than kissing another guy once)he'll ask me something about one of the times we were intimate, and I've only just told him that I don't really remember most of the times we were intimate, because I blacked out...Is this normal for people who are abused? I was abused sexually (only had fingers inserted into me once that I know of, but some of the things my father did when I was really small are suspicious, and we know he enjoys younger girls that are my age and my sister's age (11)) and my father did things like tickle my breasts and pinch/slap or press his crotch against my butt when I was doing dishes or bent over doing chores...also when he hugged (he still does this but I tend to find ways to get out of it) he would life me up and press his parts against my crotch and squish my breasts. And also I was abused physically, a lot, and verbal abuse was something that happened many times in the period of an hour...I don't have to see my father very often anymore, although my sister is forced to, so when they see each other I sometimes see him(like when he picks her up). So that's good...

I hadn't had the blackouts for awhile, and I'm thinking that it's because I'm with a guy, as I never got scared when I was dating girls (just the usual 'is she going to like me?' nervousness).
But I really want to be able to have an intimate relationship with my boyfriend, without being so afraid, I know it hurts him when I'm so scared of him...Like...when he gets mad at something or someone, I tend to freak out, if we're sitting, I tend to curl into a ball at his feet and hide my face, and if he yells or curses I start to shake...he doesn't do that very often though, just like...when he gets hurt or his sister knocks all his stuff over or breaks it or something...but I still get really scared that he's going to take it out on me, and belt me across the face or something...I've talked to him about this (because it's pretty obvious I get scared, and he keeps comforting me that he isn't going to hurt me, ever)...What can I do to not be so scared all the time?

I feel really bad, because he takes really good care of me...although we broke up a few times with our first relationship, that one was nasty, and I'm a bit paranoid that he's going to break up with me, even though we are planning to get married next year so we can live together...but I still feel bad about that breakup...the things said hurt a lot, but he says although he meant them at the time, he feels differently now...like...he said the other girl was sexier than me...and kinda...stopped paying attention to me when she was around...she was also willing to do the long passionate kisses in front of as many people as possible (she was...very into showing off her body and her 'sexiness')...and after we broke up he called me many names, and didn't want anyone we had both been friends with to talk to me...I really am afraid that something like that will happen again...there are at least three girls who want to date him, or at least have sex with him, although there is no sign of him breaking up with me right now...am I just being a bitchy jealous girlfriend that guys hate so much?

Gah...so many questions...I really hope some of you can answer them! Anything helpful would be greatly appreciated...
