I'm 19, and, this is my first real relationship, so needless to say, I am completely and utterly inexperienced. Hell embarrassingly enough, my first kiss was with this girl..But anyways, my girlfriend and I were making out last week, and I sort of kissed the top of her breast, essentially what was exposed with her shirt, but I have no idea the best way of stimulating her actual breasts.
So how should I proceed when kissing and touching her breasts ? I realise that they are more sensitive than other parts of her body, so of course I'd start pretty gently, but should i just kiss and run my fingers around her breasts and then slowly move towards her nipples? Im just winging it right now, and dont want to acidentally do something taboo and ruin the mood. Thanks.
