I'm 20 years old, from Bath, United Kingdom but studying in Cornwall.
I've recently started dating someone and it's been going on for a few months now. What makes this particularly special is that I've never felt this way about another person before. I mean, I've been romantically involved with a girl before but this time it's different.
We have pretty regular and intense s** and we do a lot of sexting when we're away from each other.
Anyway, throughout the last few months she's occasionally talked about how much she'd love a threesome and every time she does I end up feeling incredibly upset and sick to the stomach.
The thought of her getting sexual gratification from another person just sends me to rock bottom. She's fully aware that I hate this, but she still drives home how hot she thinks it'd be and I know I wouldn't last 5 minutes before having to leave the room if ever it came to be.
It leaves me feeling entirely inadequate and that I am not, nor will I ever be, really enough for her.
I know these thoughts are entirely ridiculous as, as she rightly pointed out, it's very irregular (particularly for a guy my age) to feel this way and not be comfortable with the idea of a threesome with two girls, but the fact of the matter is that I do feel this way.
I know I could never speak to her properly about this because it'd be selfish of me to put this on her.
Please, if anyone out there has any advice can I get some help? Like I said, she's so important to me and I'd hate to lose her just because I'm being frigid.
