So, last night I made a very careless descision that is currently not making me feel so good about myself. For those who go on my community profile would know that I do have a boyfriend but unfourtunely he's in jail and probably going to be on there for longer than we've known each other. I'm still not completely recovered from that either. So anyway last night me and this dude that I've known for a good 5 months finally met each other in person and we've kinda had this online relationship where we would always avoid each other or barely text due to both of our busy lives. He's a barber, and I'm always caught up in school work. So anyway he messaged me at about 3 am last night asking if he could "pull up" ehh I said why not so yeah. After about 40 minutes he showed up to my house and mind you guys we live in 2 different cities so yeah he was outside right so yeah I got in the car with him and we talked for a bit, and he started touching me in places and you guys this guy is 21 years old. I'm sure he knows all the right places to touch a girl and I stupidly fell for it so I noticed one thing he was obsessing over the whole time we were in the car was the fact that I'm so small (body wise) so yeah he's just holding my abdomen staring into my eyes and you guys I was so weak at that moment. I got caught up in how his skin complextion complimented his eyes and yeah I'm sure all females around this time is familiar with the term (lightskin) if you're African American you're well familiar with that so yeah I was really trying to stay strong (his body is incredible too not to mention.) but my inner whore was reavealed much too soon so yeah. After we had sex we had a conversation about random shit and everything got silent for a moment and I started to think about my boyfriend and I became extremely emotional so he ofcoursed ask if I was straight (okay) so I asked him if I could trust him, he said yeah so I told him I had a boyfriend and I told him my situation with him being in jail and stuff and he was understanding. Then that's when he told me that he had a girlfriend.... And she was pregnant too. I mean I kind of just brushed it off because I have once in my life time had sex with a guy that had a pregnant girlfriend but it was ofcourse protected that time and this time. So yeah the conversation got awkward because he didn't seem too bothered about the fact that he was cheating on his pregnant girlfriend. So yeah shortly after that, I eventually went back into my house at about 4:30 am. So yeah I told my sister what happened that night this morning and she was just so disgusted in me and went into this speech about how I have no respect for relationships and about how I'm not considerate of other females feelings and how hurtful that could be to a pregnant women. (Basically harshly criticized me.) She made me feel bad about the fact that I've done that twice in my life already and also being skinny, she said to me these exact words, "do you even regret doing that? Just think about your spouse in the future lieing to you about where he's going to at night while you're about 5-6 months pregnant when in reality he's going over to a thin 16 year old girls house to have sex with her and love on her body." I felt so suddenly gross about myself and of course I can't help the fact that I'm skinny but I don't want it to seem as if I'm more attractive than a pregnant women because my stomach is flat. So yeah my question is are pregnant women really self conscience or is my sister very sensitive on that subject because she was pregnant before and currently is (4weeks). And you guys I really didn't know that this dude had a whole girlfriend and a baby on the way till afterwards Advice??? And can someone answer my question??
