are you really going to listen to any advice given?
i have behaved similarly in the past, with hindsight i think i was seriously unhappy/ unfulfilled, it resulted in 2 pregnancies of course. because that is what unprotected sex eventually leads to, unless you have fertility problems
it's seems a mysterious and slightly unbelievable occurence, pregnancy..can it really be the outcome of sex? what will my life be like if i have a child?
wake up and get a grip tonight! the reality is that parenthood is horrible with the wrong co-parent, being a single parent may be better but the best you should yearn for is to wait for the man who will be the life partner you deserve and the father you want for your children then go for it
perhaps it's your present situation, final year at uni- uncertain future, realisation that you're ready to move on from boyfriend, that is making you yearn for the 'simple life' of a baby..
but it's hell at times having a life that's patching up bad choices and making the best of difficult situations.
do yourself a massive favour, start taking contraception seriously, buy some larger condoms (my dh is huge and durex fetherlite are fine, it's probably extra lubrication you're requiring so buy some lube/ ky)
and wait until you're in love/ already settled/ had your years living together and are both ready for a baby
