I had sex for the first time with my boyfriend and while the foreplay was nice...his penis is so small that by the end it had slipped off him and ended up in me.  It was the most atrocious thing ever!

I mean he is very nice and all...but I got more pleasure from his fingers then from intercourse and I would rather have more pleasure from intercourse.  I mean I even found myself thinking about my ex again...who had a wonderful sized penis.  What do I do?  I mean I want/need sex to be a part of my relationship.

I think you meant to say the condom slipped off him and wound up in you.  I don’t believe that it was “atrocious” in and of itself, though it could have exposed you to an unintended pregnancy. It’s not going to help if you exaggerate the problem. Second, you both should know that condoms come in different sizes. There are condoms with a tighter fit that are sold in most drug stores, and Condomania sells condoms in 70 different sizes, so that he could get a custom fit. That would cure that particular problem.

There aren’t a lot of options concerning the actual size of his penis and how much feelings you get from intercourse. One option is that there are rubber sleeves that are sold by some stores or websites that carry erotica that can make his penis feel bigger to you. But the main question is, does he give you orgasms, if not through intercourse then by other means? If he doesn’t, then that’s a problem that needs to be taken care of first. He can use his fingers, his tongue, a vibrator or his big toe to give you enough clitoral stimulation that you get sexual satisfaction. Then you can decide whether his overall qualities – his personality, sense of humor, etc - outweigh the fact that you don’t get as much pleasure from intercourse as you would like. That’s a personal decision that only you can make, but unless you already know that he’s not worth it, you shouldn’t judge his sexual qualities until you find out whether or not he can give you orgasms without his penis being involved.
